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:
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.

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.

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.
