hmm, can you send the output of "cat /proc/bus/usb/devices"? Also, USB defines (in table 9.10) the bMaxPower to be expressed in 2 mA units, so a value of 250 means 500mA. I'll add the conversion in UsbView... >Queueing will be great to have. I've also seen errors -110, then unplug/plug >of cables and rmmod are of no help, reboot is the only way out.

Yep, the linux kernel USB support, especially for UHCI Host Controllers, has some problems. And, hotplug really complicates things - it can take a long time to finish. If you look at the hotplug script (in Redhat 7.3 at least) there's a 3 _second_ sleep put in there! It's getting a lot better in the 2.5 kernel, tho. >Sorry for the delay, thanks for testing this out!
