[zd1211-devs] firmware timeout issues (error -110)
Hi Devs, I hope someone can shed some light on why I am seeing these errors. When using the standard zd1211rw, mac802111 cfg80211 drivers that come with fedora 14 (2.6.35.13-91) i am able to run my zd1211-based device perfectly without a glitch over a 10m UTP usb extension. I can even run airodump-ng for days on end without a glitch (of course no packet injection or signal level feedback). However when I try to use the compat-wireless-2011-05-26 or compat-wireless-2011-04-22 drivers I receive firmware timeout errors.

Re: [zd1211-devs] firmware timeout issues (error -110)
Hello! This is interesting bug. The device actually presents itself differently to host depending if it's running either USB 1.1 or 2.0. As I tested zd1211rw AP-mode only on USB 2.0, result was that zd1211rw expected to always see device as it seen on USB 2.0. On OHCI-host this triggers error in ohci_hcd when driver tries to communicate to device (and correct error message appears only with zd1211rw debugging enabled). Patch attached fixes the problem. You can get patched compat-wireless tarball from: http://koti.mbnet.fi/axh/kernel/zd1211rw/compat-wireless-2011-05-28-zd1211rw_fix.tar.bz2 -Jussi Quoting Jussi Kivilinna jussi.kivili...@mbnet.fi: Hi, I have reproduced the bug, happens only on ohci_hci (not ehci or uchi).

I can even run airodump-ng for days on end without a glitch (of course no packet injection or signal level feedback). However when I try to use the compat-wireless-2011-05-26 or compat-wireless-2011-04-22 drivers I receive firmware timeout errors.
