Hi there,
One of my control messages is returning 'EPIPE' when my system is under
heavy load. I'm stumped; does anyone have any suggestions?
It's not an endpoint stall (clear_halt() fails). 90% of the time, I can
work around by re-issuing the request (once). But the other 10% of the
time, *both* requests succeed--even the original one that returned
-EPIPE.
Here are the details. It happens:
-under heavy load (high disk activity)
-uhcl chipset only (ohcl and ehcl behave)
-linux 2.6.x (2.6.8.1, 2.6.9-rc3)
-iRiver iFP-5xx device
-usb_control_msg()
-always the same control message. (One requesting bulk data.)
Any suggestions, advice or insight would be most appreciated.. thanks,
Geoff
