Hello,
for several days I ways trying to get devel/avrdude to work with an
USBasp compatibel device (www.ullihome.de) on FreeBSD 7.2 running as a
guest in VMware Workstation 6.5.2.
Because avrdude didn't recognize the device at all, I had a closer look
and found that nearly (I am not sure enough to say every) second control
transfer (using libusb's usb_control_msg) fails, if:
* it is a read request (has USB_ENDPOINT_IN set) and
* requests more than 20 bytes (ucr_request.wLength). If 20 or less
bytes are requested, most (not sure if all) transfers suceed.
To repeat run the attached program:
1. Fill in some vendor / product ID of a device detected as ugen device
2. Compile and run the code (devel/libusb must be installed).
The result will look like this:
root@kirika2# ./test
Found AVR-USB device
USB_control_msg result: 28
1c 03
Found device from vendor: www.fischl.de
USB_control_msg result: -5
Warning: cannot query product: error sending control message:
Input/output error
I built and ran a kernel with USB_DEBUG enabled and set 'sysctl
hw.usb.ugen.debug=6'. The result is attached. Excerpt:
kernel: ugenioctl: cmd=c018556f
kernel: usbd_alloc_xfer() = 0xc36eb800
kernel: usbd_transfer: xfer=0xc36eb800, flags=6, pipe=0xc37a7480, running=0
kernel: usbd_dump_queue: pipe=0xc37a7480
kernel: usb_insert_transfer: pipe=0xc37a7480 running=0 timeout=5000
kernel: usb_add_task: task=0xc36eb990
kernel: usb_task_thread: woke up task=0xc36eb990
kernel: usb_transfer_complete: pipe=0xc37a7480 xfer=0xc36eb800
*status=15* actlen=0
The USB_DO_REQUEST (0xc018556f) ioctl to ugen times out. I can set
different timeout values (tried 1000, 5000, 10000), it times out everytime.
If the same request is send immediately a second time (for example by
putting the usb_control_msg call in a loop) it suceeds!
Some remarks:
* This only happens running FreeBSD 7.2 in VMware, it does work on
real hardware (see below)!
* Avrdude with libusb-win32 is running fine on WinXP as guest OS.
* It does happen on different hosts running VMware (all Windows
hosts anyway)
* It happens no matter what USB device I tried (used USBasp,
lcd2usb, Garmin GPS, USB smartcard reader)
* It is reproducable on my systems.
On real hardware, the program results in:
test# ./test
Found AVR-USB device
USB_control_msg result: 28
1c 03
Found device from vendor: www.fischl.de
USB_control_msg result: 14
0e 03
Found device: USBasp
So what could it be?
Regards,
Markus
