EHCI driver on Nvidia hardware

[Jonathan A. Kollasch]

Hi,

I've been trying to use a flash drive on a nforce4 board that runs
SeaBIOS.  It doesn't work very well, it often fails with a timeout
in ehci_wait_qh() before even detecting the device.

Thanks Jonathan,

I've seen an occasional timeout as well.  However, it works more times
than not for me.

I got a report last month that:

pipe->qh.token = QTD_STS_HALT;

in ehci_control() causes controller crashes.  Maybe this is impacting
your chipset as well?
