[zd1211-devs] zd1211rw timed out on ep4out
Hi! On kernel 2.6.19.2, zd1211rw, VT82x UHCI USB 1.1 Controller (rev 0e) 1106:3038, Longshine G2 07b8:6001, the driver hangs pretty often with the following error messages: usb 1-2: zd1211rw timed out on ep4out len=0/6 zd1211rw 1-2:1.0: zd_usb_ioread16v() error in usb_bulk_msg(). Error number -110 zd1211rw 1-2:1.0: zd_chip_control_leds error -110 (repeated indefinitely) Unplugging and plugging in the device TWO times helps (for a short time). Seems this or similar things happen quite often on VIA-based USB 1.1 controllers - on another machine using VIA USB 1.1, I saw similar effects, but there for some reason the USB layer dealt with the problem after some time (to the driver, a disconnect and reconnect event was shown - without manually interfering). Any idea how to solve this (apart from getting a new USB controller, this is work in progress here ;-)? Regards - This SF.net email is sponsored by: Splunk Inc.

For your iw_stats changes this should be straightforward - for skb-mac.raw it's probably better to find out what exactly happened to the field. If you do that and submit the patch (best send it to me directly, too) I'll include it in SF SVN trunk. Regards - This SF.net email is sponsored by: Splunk Inc.

The error -110 is a timeout. It simply means that the USB subsystem couldn't execute the USB transfer. We had comparable issues witht the mac80211 stack and I implemented here some controls to limit the number of USB packets to be queued for transmission. At least in my experience this limited the -110s for zd_chip_control_leds(). The device hangs might result from an unsuccessful reassociation, which is sometimes requested from the AP. It could very well be that the support for VIA USB host controllers is pretty weak in the kernel. I have a VIA-based USB 2.0 card in my oldest PC and it is consuming 10% of computation time on Linux box. Beside this the systems works well. But notify that I'm currently only developing the mac80211 driver. Regards, Uli -- Uli Kunitz - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

[zd1211-devs] New device ID for zd1211rw driver
Hello, I'm writing to contribute a new device ID for the zd1211rw driver. Product: ZyXEL M-202 XtremeMIMO USB Adapter USB IDs: 0586:340a Chip ID: zd1211b chip 0586:340a v4810 high 00-13-49 AL2230_RF pa0 S FCC ID: SI5WUB221Z Driver code: { USB_DEVICE(0x0586, 0x340a), .driver_info = DEVICE_ZD1211B }, I have successfully used this configuration in a WEP-encrypted infrastructure network.

It's very interesting: MIMO is the technology used to drive 802.11n (multiple simultaneous data throughput channels) but the ZD1211 hardware does not support this (it only has a single radio). The ZyXEL website doesn't really explain how they are using MIMO in this device. Just curious, do you have any ideas? I checked the windows driver and it does seem to be just a ZD1211B, nothing new... I'll submit the ID addition in a few minutes. Thanks! Daniel - This SF.net email is sponsored by: Splunk Inc.

The extent of my knowledge about this product is that it ran me about $12 last week from TigerDirect :-). It claims to have three antennas inside its little box - pointing up, left, and right - with LEDs indicating which one is in use. Oddly enough, the same LED lights up regardless of how I orient it w.r.t. the AP. I also notice that all the literature calls it 802.11g - not 802.11n. My guess is that it's a garden variety, gimmicked-up 802.11g desktop dongle. Nathan I checked the windows driver and it does seem to be just a ZD1211B, nothing new...

Someone should tell ZyXEL that's called antenna diversity, not MIMO :) I wonder if they do diversity/antenna switching externally from the ZD1211 hardware. If they use ZD1211 functionality for diversity, it may explain why the current antenna never changes: our driver doesn't support the ZD1211 diversity features (and neither does the vendor Linux driver really). One interesting test would be doing the same experiment under windows and seeing if the lights change. Daniel - This SF.net email is sponsored by: Splunk Inc.
