Greg, this would be a USB thing and not a dwmw2 thing, yes? It's apparently a 2.6.16 regression :( Yes, it's a USB issue Alan, have you seen this config error before? It sounds familiar... I don't recognize this particular error. And I don't know of any changes in the last kernel release that would cause this sort of thing. It's faintly possible that the device itself has recently broken. Roman, could you please compile a 2.6.15 kernel and a 2.6.16 kernel with CONFIG_USB_MON and CONFIG_DEBUG_FS (as well as CONFIG_USB_DEBUG)? Then follow the instructions in Documentation/usb/usbmon.txt, and attach here the record of the USB traffic under each kernel when you plug in the flash device. Comparing the two logs may show where the problem is. Also, please provide the contents of /proc/bus/usb/devices (you may have to mount /proc/bus/usb first) or the output from "lsusb -v", with the device plugged in. Best to do this under 2.6.15, where it will work okay. Ok.
Now I have 2.6.15.6 and it works!
Thus, the device is not broken.
I don't know whether it's important or not:
I have forgotten to note that It's all in 64-bit mode. I have no 32-bit
distro installed, so had not tested in 32bit yet.
And also I have another Samsung 16Mb flash which works fine with 2.6.16 !
I'll do usbmon instructions later. Some details with 2.6.15:
The following is apparently erroneous(broken pipe), but flash works fine(why!?).

my kernel config
my kernel config
It sounds like the Apacer device isn't fully functional. I need to see the usbmon output to say any more than that. The fact that you're using 64-bit mode shouldn't make any difference. Everything is supposed to work just as well as in 32-bit mode. Created attachment 7974 [details]
2.6.15 usbmon log on plug
I have started usbmon, plugged flash, stopped usbmon.

2.6.16 usbmon log on plug
Interesting thing: when I plugged in flash running 2.6.16 and restarted without
replugging to 2.6.15 - during boot the kernel(2.6.15) argued with error "-32"
and smth like that. I unplugged flash and it continued booting. I plugged in
the device and it works fine again with 2.6.15 . So there is some hardware
state associated with the device which persists after unsuccessful plug.
From the usbmon log I can see the problem. 2.6.16 sends a Get-Device-Status request which the Apacer doesn't like, and after that the device stops working. 2.6.15 doesn't send the Get-Device-Status request and consequently has no problems. This is definitely a bug in the Apacer firmware. Get-Device-Status is a standard USB request and all USB devices are required to support it. I can't think of any acceptable change to the kernel for getting around this problem. However, you can always patch your own private copy of the source code to eliminate the Get-Device-Status call. To do that, you have to edit the file drivers/usb/core/hub.c. Find the choose_configuration() subroutine; near its start there is a call to usb_get_status(). Comment out that line or delete it entirely. That should solve the problem. Thanks! I'll try your suggestion later. Perhaps kernel should post a warning to the log instead of stop working with the device? I hope the bug won't go into WILL_NOT_FIX or INVALID state. I'm not familiar with log systems, but it should be nice to have some kind of classification of log messages and an ability to make listener to put that message to the tty/X/gnome/kde environments to make it as fancy as ms has. I think it would be good for linux4desktop direction. The kernel stopped working with the device because there was nothing more it could do when the device wouldn't respond. There _was_ an error message posted to the kernel log. You saw it yourself: "usb 2-10: can't set config #1, error -32". I admit that this doesn't give much detail about what went wrong, but then the kernel itself didn't have any detailed knowledge about the problem. All it knew was that the device had failed to respond to a Get-Device-Status and a Set-Configuration request. This bug report should be REJECTED because it is not a bug in the kernel; it is a bug in your Apacer device. There _is_ a classification of log messages. They are classified as DEBUG, INFO, NOTICE, WARNING, ERR, CRIT, ALERT, or EMERG. This particular message was at the ERR level. Userspace tools can and do use the message level to decide where log messages should be sent. If you had been running a console window in your X/gnome/kde session you undoubtedly would have seen the error report. Created attachment 8015 [details]
Remove trouble-causing GET_DEVICE_STATUS call
It turns out the trouble-causing Get-Device-Status call isn't being used for
anything important, so getting rid of it won't cause an inconvenience. The
attached patch (for 2.6.17-rc2) does just that. Let me know if it solves your
problem.
I was lazy to download 2.6.17-rc2 to apply that patch clearly. I've commented out those lines manually in 2.6.16 in drivers/usb/core/hub.c and apacer flash stick works now. I suppose there should be no problems with 2.6.17 + patch and it will work. When 2.6.17-non-rc will come out - I'll necessarily try it. Thanks for advice ! looks like this bug can be marked "resolved" now... |
