Sarah,
Pardon the intrusion, but I'm trying to fix a problem for v4mp, a user of the
rtl8192cu driver on an Alfa AWUS036NHR. I have one of the devices, and it works
on a USB 2.0 hub, but fails with 3.0 hardware with lots of
xhci_hcd 0000:05:00.0: ERROR no room on ep ring
messages logged.
The device works with an out-of-kernel driver available from the Alfa or Realtek
web sites, but I want to fix rtl8192cu.
What condition leads to the above message? The user's dmesg buffer has wrapped,
thus I don't see the beginning of the failure. He is using a canned distro
kernel, thus he cannot include any extra debugging info such as a stack dump
when the errors occur. As he uses the compat-wireless package, I think I can
incorporate a new copy of xhci-hcd with it, but I have not done so yet.
Thanks for any help you can give,
Larry
