Several weeks ago GetUSB heard that external USB 2.0 devices may cause certain notebook computers to consume power excessively. In the interest of tracking down the source of the problem, Tom’s Hardware Guide worked with engineers from both Intel and Microsoft. Through their extensive collaborative research, they reported that an Advanced Configuration and Power Interface (ACPI) driver in Windows XP Service Pack 2 is the sole cause of the unusually high power drainage observed by all three teams. Today, Microsoft confirmed that it is developing a new patch to fix this particular driver bug, whose nature is somewhat different of those addressed by earlier Microsoft Knowledgebase postings.

Atmel, a global leader in semiconductors, announced USB and OTG (On-The-Go) in the AT90USB family. Several products in the AT90USB line have USB interface for applications needing to communicate with USB host. The AT90USB1287 and AT90USB647 comply with the USB OTG standards for use as both host or device. The USB host capability is key to embedded devices needing to communicate without PCs, a good example of this would be transfer of data between two devices without a computer, i.e. from camera to printer for On-The-Go productivity.

Windows Automotive and Fiat are poised to unveil a new in-car technology via USB called “Infotainment.” This Bluetooth based technology will interact with hand held devices like phones, PDAs, GPS systems and other communication devices. Connection is made from a hardwired USB port located in the glove box to the internal car system. Voice activated features, like reading SMS messages, playing MP3 files and more
One of the necessary evils of migrating from aCD player to a digital music player is the tedious process of extracting music from already owned CDs. Sure, anyone with a computer can use one of the available music extraction software programs, many of which are free. But for those that don’t have access to a computer, or that don’t want to tie up their computer system resources while “ripping” CDs, there is another option. EZPnP is perhaps best known for their EZDigiMagic CD Burner, a standalone device which removes files such as digital photos from memory cards, and then burns that data to a CD. They have now introduced the EZDigiMusic MP300 which basically does just the opposite. Instead of copying data from a memory card to a CD, it copies music files from a CD and converts them to MP3 files which are then placed directly on a memory card or onto a connected USB enabled flash memory device.
