Hello First of all make sure you have the latest kernel run rpi-update(google how to install it). This is a big improvement in usb functioning. I looked at the site and it seems that your adapter is an DS2483 with some usb serial adapter. This is not a good solution. I personally does not have any experience with those but I've read people have problems with usb serial adapters like FT232.
Second you could also try to force usb 1.1 this should help however the LAN(it's also on USB bus) performance could be limited. dwc_otg.speed=1 http://raspberrypi.stackexchange.com/questions/1886/what-kernel-parameters-are-available-for-fixing-usb-problems I doubt it's a power problem. If your power supply is truly 2A. You can check the voltage on the board TP1 TP2. Which version of Raspi board do you have? The most recent ones have usb polyfuses removed so there shouldn't be any significant voltage drops with good power supply. I run a power hungry 3G modem directly form little modified first version of Raspi. 1 ohm resistors added over usb polyfuses and some extra caps.Here is the thread with modifications http://www.raspberrypi.org/phpBB3/viewtopic.php?f=63&t=8591&p=210186#p210186 I have a "original" power supply from RS Components. I can even plug and unplug the modem and Raspi does not restart. Raspi(v2) usb ports are directly connected to 5V rail so when you connect some device which has ceramic capacitors inside(almost every device) they start to charge. Those caps can charge very fast so for fractions it's like a shot circuit. For more detail information you can read the thread it's explained there why this works. Or ask here I will try to explain it however I'm not an trained electronic engineer. There where sucess reports of usb 1-wire adapters here but I can't rememberer exactly which one it was. Perhaps the "native" DS2490. -- p4trykx ------------------------------------------------------------------------------ The Go Parallel Website, sponsored by Intel - in partnership with Geeknet, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials, tech docs, whitepapers, evaluation guides, and opinion stories.
