Is it possible that some other piece of hardware (non-USB, and non-USB host chipset) is impacting this? The only reason I ask is that I have a PCI wireless card that is using the kernel rtl8185 driver (which thus far could best be described as "functional") and network traffic often gets dropped for several seconds. Is it worth unloading the rtl8185 module and seeing if that makes a difference? Also, would more output from dmesg (or any other command) be helpful? > I'll have to take a look at the code and see what I can figure out. > Do other high speed USB devices work with your host without any > problem (like USB hard drives, etc?) > The only other devices I have attempted to attach are a 2GB flash drive and a wireless keyboard/mouse combo. Those devices work without any issues, but I don't think they qualify as "high speed." I do have a USB 2.0 hard drive, though. I'll hook that up and see what happens. Thanks again! John
