Hi

I managed to get the snd_usb_usx2y driver running on an Linksys NSLU2. The whole stuff is running under debian etch.

Kernel Version is 2.6.18 with Debian patches. Below is a little patch to be able to enable the driver. Unfortunatly the driver gives the error:

Sequence Error!(hcd_frame=7 ep=8in;wait=65539,frame=3). Most propably some urb of usb-frame 65539 is still missing. Cause could be too long delays in usb-hcd interrupt handling.

Which is the output of the function usX2Y_error_sequence. This function is only called from usbusx2yaudio.c:328. Since all numbers lie just above 65535 (They are all between 65537 and 65540) is suspect that there is some wrap around error, especially because the values are anded with a 16 bit mask (0xffff). But unfortunatly i don't know to much about usb right now. Any hints to resolve this problem?

The cpu runs with 266Mhz, so it could be that it would be really to slow, but i really suspect an wrap-around error. Any hints or ideas to solve this issue?

Thanks ST
