Only 1 USB Drive Can Be Use – Others Are Ignored

The most common reason why only one flash drive is usble when multiple USBs are connected is due to a device signature collision.

If you are dealing with bootable devices and seeing this problem, we are confident a collision is the issue. If you are not dealing with a bootable device, then our information below will, probably, not help.

What is a USB signature collision?

A signature collision can happen on any bootable device, so Compact Flash cards, SD cards, microSD cards and USB flash drives. A disk signature is a unique identifier number (UID). It is a unique identifier stored as part of the MBR (Master Boot Record) for an operating system loaded on the device. The operating system will use the UID to identify and distinguish between storage devices. It is commonly made up of eight alphanumeric characters. A disk collision occurs when your operating system (Windows) detects that there are two disks with identical signatures.

For Windows 7, 8, 8.1 and 10, these versions of Windows will disable the second drive and will not allow that second volume to mount until the disk collision has been rectified. If you are reading this article, chances are, this is exactly what is happening to you.

The first thing to do is navigate to the Disk Management tool with in Windows. To do this, use the search tool and type in Disk Management. This will take you to the utility that Windows offers. Here you can see your multiple devices connected. If you click or hover over the device not working you will see one of two messages:

Commercial Grade USB Solar Charging Station

Legrand now offers the XSOLARCS USB charging station for public works, schools, parks and transportation centers.

With the Legrand solution, there is no construction required in order to install the charging station. The unit is a self contained solar panel tower, with six USB charging ports pulling from the solar panel. There are three shelves which can mount in adjustable locations to the panel tower poll. Each shelf containes two USB ports with up to 3.1A of shared power between them. There is no trenching required or other expensive construction projects in order to get the EXSOLARCS going.

USB sockets are protected from the eliments with a sliding door in front of the two port socket assembly. Not only is there protection, but LED illumination at each port for after-dark identification and ease-of-use. If the light is illuminating, the station can provide a charge. This implies there is some type of battery inside the station, which we’ve emailed Legrand to find out exactly what.

The XSOLARCS was designed with the elimints in mind. The USB charging station is designed to withstand hurricane-force winds and has the full RoHS certificate compliance.

Flash Drive Prices Are Going Up – Cause: Japan & S. Korea Trade War

Japan has been a long time supplier for three key elements used in the manufacturing of NAND memory and semiconductors. Because of recent trade war issues between Japan and South Korea, these elements are getting very hard to obtain.

Japan produces about 90% of the world’s supply of flurinated polyimide and resists, and about 70% of the world’s supply for hydrogen fluoride. This puts everyone at risk if Japan will not supply those demanding it.

Those chemicals are used by Korean manufacturers to produce semiconductors, and are crucial for making components — including memory chips, microprocessors and integrated circuits.

We have seen the direct impact already. For the first time in over eight months, the price of NAND memory for flash drives have gone up. For each GB capacity the percentage increase is different, but most notably are the 32GB and 64GB wafers. They have jumped nearly 25% from the previous week ( this article was posted on July 25th).

Japan has sited inadequate management of those chemicals by purchasing countries. Said another way, these chemicals can also be used to manufacturer military weapons and Japan is claiming those supplies have been diverted to do just that. Japan’s response; restrictions on the chemicals.

Who will lose from this trade war? None other than any person who uses technology. Cell phones, processors, flash memory, circuit boards, the list goes on.

To learn more about the polyimide chemicals a quick read on this wiki page is fairly interesting. Continue Reading

Off Topic: Interview with Nexcopy CEO, Greg Morris

Nexcopy is a bit of classic entrepreneurial story, starting out in a home garage and sales on the first day of business, this is a story about a copy that has gone only upward.

Tech Company News had some time to sit down with the owner of Nexcopy, Greg Morris, and fire off some questions.

Here is a snippet from the interview…

Question: What kind of technology does Nexcopy offer?

Answer: Nexcopy has a specific focus on flash memory duplication, printing and production needs. The business started out with one product geared towards USB duplication. From that single product, Nexcopy’s business has expanded into other duplication equipment such as SD card duplicators, microSD cards duplicators, Compact Flash cards duplicators, and of course our most recent product, the USB Type C duplicator. During this expansion process of hardware, Nexcopy also developed copy protection of digital files on USB drives and mobile devices. Several years ago, Nexcopy introduced a USB flash drive printer which really rounded out our product offering. From the devices, to the duplication equipment to the branding equipment, Nexcopy is a one-stop manufacturer for anyone who deals in flash memory.

The full Nexcopy interview is available on the Tech Company News website.

QuadCore Raspberry Pi 4

Update:

From this article, the Raspberry Pi 4’s USB-C power port was designed outside of official USB-IF specifications, making it incompatible with many USB-C chargers and/or power supplies. You can read more about from the link above and the information gathered to come to such a conclusion was done by a well known Google engineer, Benson Leung.

The raspberry Pi is a collection of small computer boards put together in a simplistic way to create the foundation of a computer system. The Raspberry Pi (also known as RPi) was released back in Feb of 2012 in the United Kingdom. The original intent of the RPi was to develop a low cost and simplistic computer which students could learn and develop.

The original model became far more popular than anticipated, and started selling outside its target market for uses such as robotics. It does not include peripherals (such as keyboards and mice) or even come inside a case. Literally a bare-bones product.

To give you an idea of the popularity, the RPi products have sold over 19 million units between its release in 2012 to the end of fiscal year 2018. This makes the RPi one of the best-selling computers in the world, although a computer with limited resources. Until now.

This week the Raspberry Pi Foundation has released the Pi 4. This is one hell of a great product. Check out these specifications:

  • A 1.5GHz quad-core 64-bit ARM Cortex-A72 CPU (~3× performance)
  • 1GB, 2GB, or 4GB of LPDDR4 SDRAM
  • Full-throughput Gigabit Ethernet
  • Dual-band 802.11ac wireless networking
  • Bluetooth 5.0
  • Two USB 3.0 and two USB 2.0 ports
  • Dual monitor support, at resolutions up to 4K
  • VideoCore VI graphics, supporting OpenGL ES 3.x
  • 4Kp60 hardware decode of HEVC video
  • Complete compatibility with earlier Raspberry Pi products

In addition to the hardware improvements, the Raspberry Pi Foundation says

Solved: Windows Will Not Assign Drive Letter To USB Flash Drive

Problem Issue:

This is happening on Win8 and Windows 10.
When I remove a USB drive and reconnect it, Windows will not assign a drive letter. Clearly this is a problem as every other computer I use assigns a drive letter.

There are three solutions. All of which will work.

      1) You can go into Disk Management and select the device and assing a drive letter. This is a manual process and not ideal for each time you plug in a flash drive.
      2) Good chance the driver or registry entry for that device is rogue or corrupt. Use this USBScrub tool to remove the registry entry. Chances are this will fix the problem. USBScrub link
      3) Use ‘diskpart’ and enable the automount feature.
  • Open Command Prompt as Administrator (search for Command Prompt in the Start Menu, right click, Run as Administrator)
  • Type ‘diskpart’ and hit Enter.
  • Once in the ‘diskpart’ command prompt type ‘automount enable’ and hit Enter.
  • Type ‘exit’ and click Enter

For solution number one from above, Disk Management is really the GUI version for diskpart, but a GUI (Graphical User Interface) which has scaled down functions from what all the things diskpart can really do.

Diskpart has 37 commands that you can do very cool things with. The 38th command is

Updated iPad OS Will Accept USB Thumb Drives

Today Apple announced the new iPadOS will support USB thumb drives. The iPad has long been toughted a workers tablet from Apple, but the relaity is their iPad didn’t provide much functionality. In addition, the devices have limited storage.

With today’s announcement the above argument could get a little muted.

Update: We learned the iPad will allow other storage devices such as external hard drives and SD or microSD cards (with USB adapters). The USB port will also allow for HID devices, such as a USB mouse and keyboard. We are not sure if the iPad will support Bluetooth mouse and keyboard, but we’ve got to assume, right!

There is no word about the connection. The connection could be one of three; an adapter, USB-C socket size or the classic USB type A socket size.

News: USB-C Duplicator Shows USB-C Product Trending Up

In a recent news press release from Nexcopy Inc., it appears USB Type C is trending up for consumer demand.

Via the EIN News Wire Service, Nexcopy announced a twenty target USB-C Duplicator.  Some of the information posted in the release talks about the upward trend manufacturers are seeing with USB type C product.  In addition, the production of a mass aggregator, or duplicator, is another indication users are data loading, in bulk, to USB-C product.

“Apple computers and Iot, or Internet Of Things, are driving the force behind the increased demand for USB-C flash drive consumption.  Although the internet is great for many data sharing applications, there is still a great need for data dissemination off line.  USB is still the definitive choice among users to share data via flash memory,” states Greg Morris, President of Nexcopy.

Morris continues, “We see the demand of USB-C duplication to only rise in the coming years.  In technology, smaller is always better, and as devices get slimmer in size the USB type A socket will eventually phase out and USB type C taking over.  The transition is slow, but it is inevitable; and with that said, we are ready – today.”

Nexcopy is also well known for the PRO series duplicators that perform advanced functions to flash drives, such as USB write protection (USB read-only), partitions at the controller level, and serial number control for UFD identification.  From the press release, these advanced functions will also be available on the USB-C200PC duplicator.

The USB-C duplicator has a list price of $1,299 from what we understand and available now through a list of on-line retails like Amazon and NewEgg.  The product is also available through a worldwide network of authorized resellers.

Will Trump Tariffs Affect USB Flash Drives?

Posted May 16, 2019.

The United States and China walked away from trade talks earlier this week. From that departure President Trump and Xi Jinping of China are increasing the number of products subject to tariffs.

With that said: Will Trump tariffs affect USB flash drives?

Doing a quick Google search there is a good chance a BuzzFeed article will come up first. In that article, the author incorrectly claims flash drives will be affected. Flash drives are not affect by tariffs at this time.

Don’t take our word for it, find out for yourself. Here is the information you need:

Here is the Harmonized Tariff Schedule link:
https://hts.usitc.gov/

The Harmonized Tariff Code for a USB flash drive is: 8523.51.0000
Simply search the above website for the HS Code number. The chart will say to the right if the product is FREE or has a % tax.
