FI is the number of bit times in a frame, i.e., 11999 bit times in 1 ms result in 12Mbit/s transfer rate. FSMPS shows during how many bit times in the frame the usb transfers are allowed. If it is set to 0, no transfers can happen. > I found that the old 2.4 driver I was using (bingo, and probably its > predecessors) set FSMPS to: > ((FI - 210) * 6) / 7 > which seems to work, although I haven't a clue what it means :-(.

Did you get the driver running under something newer than 2.6.9? Is it 2.6.10? I wrote the driver on 2.6.9. There the definition is present. Had no time yet to port it to 2.6.10. > I also copied the sw reset logic from the 2.4 driver, with the current > sw reset I see a hang shortly after the usbstorage driver is finished > initialising but with this change everything is OK. Thanks for the sw reset code. It works also here. I have used hardware reset until now. > BTW I also remember reading that lowercase is frowned on in CONFIG > options. Yeah, fixed this. Thank you for the feedback! Good to hear you got it running.
