I am trying to get Netgear MA111v2 wireless USB card which uses SIS163u chipset to work with ndiswrapper (tt doesn't have a native driver or specs). After much reworking of USB layer and other support added for it in ndiswrapper, the device seems to initialize partially (shows proper MAC address etc.). However, after exchanging lot of URBs, the device seems to have died. Close inspection reveals that when reading a URB it fails with EILSEQ. At that time, I see following message from kernel:

When ehci-hcd is not loaded, I don't get the initialization errors, but submitting URBs result with the same errors. Although the device driver binary (Windows driver), I can provide dump of any URBs that are received from/sent to the driver with ndiswrapper. If you need any further info, please let me know.
