I have 3-5 PC, Laptop etc, and 5-6 different model USB Stick. I plug a stick to USB, many times it's identified normally. Mount etc.. OK.
But, sometimes system don't identifiy USB stick. According to dmesg, its can't read from device with error -110 (or -70, sometime but not frequently). I remove UHCI, EHCI, OHCI drivers, and retry with one driver. Sometimes EHCI can be solve, sometimes UHCI. But, if i plug stick to any other USB socket, this problem can be re-occur.. I Don't see any extra position, state etc. for this problem, i think its a completely randomly reason. I use, Linux 2.6.10 vanilla, MDK 10, Mandriva 2005, Fedora 3/4. Many PC's have recompiled kernels. All systems infected :( I think a reason for this problem, but don't sure: If EHCI+UHCI modules and USB 1.x / 2.X controller present, and a device plugged, EHCI or UHCI can claim this device, but device plugged to other controller. If only EHCI presented and only 2.0 controller used, this problem can't occurred (or only 1.1 and UHCI module). Do you have any information for solution of this problem?
