After some experiments, I found some problems in writing to ZD1211 control registers. After "successfull" write, re-read returns old unchanged value. For example: u32 enc; int r; r = zd_set_encryption_type(chip, ENC_SNIFFER); /* ENC_SNIFFER == 8 */ /* Verify r is zero. */ zd_get_encryption_type(chip, &enc); /* Now should be 8 (ENC_SNIFFER) in enc variable. But sometimes (5-10%), is 0 (previous default value) here. */ Sometimes, any timeouts (-110) and other problems occurs. I have modified driver to write/verify/retry-write scheme, and it works. Yes, it is stupid, but I don't know real cause of this problems and this solution works almost good. Take this as hint without guarantee, you may have or not the same problems caused by USB 1.1. I have very exotic system - our own hardware, with some known and maybe any unknown HW bugs and zd1211rw driver mixed from 2.6.18 stable kernel, CVS sources and my modifications. good luck, Tomas -- View this message in context: http://www.nabble.com/%22zd1211rw-timed-out-on-ep4out%22-tf4219193.html#a12629708 Sent from the zd1211-devs mailing list archive at Nabble.com. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
