OK, I tried uhci.o on an unpatched 2.4.2 kernel:
- Plugging in DSB-C300: Same result, no messages at all. Same fix.
- Switching KVM: cannot reproduce reliably enough to test it.
- Plugging in 3 cameras: works. Plugging in 4, however, gives me repeated "error -110"
and "error -71" messages. I had to unplug all upstream and downstream cables from the
hub to get it working again.
So, it looks like this is a general Linux-USB problem. Either that, or it's a problem
with my specific hardware (i82371SB PIIX3 USB [Natoma/Triton II] Rev. 1). I will try
this on my trusty OHCI tomorrow.
