Re: [panic] Race in IEEE802.11 layer towards device drivers

If the drivers don't panic to begin with, we won't know the patch really fixed the issue. No, I think it is safe to remove it. --HPS ___ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to freebsd-usb-unsubscr...@freebsd.org
Re: read(2) always returns 0 when reading from /dev/usb/n.m.k bulk IN endpoint
Hi, FYI: just tried using the short xfer ioctl, but the behavior didn't change. in = open (argv[0], O_RDONLY); ioctl(in, USB_SET_RX_SHORT_XFER, 1); n = read(in, buf, NBUF); now trying libusb for this. -- Peer On Mon, Jul 12, 2010 at 10:41 PM, Peer Stritzinger pee...@gmail.com wrote: Hi, On Mon, Jul 12, 2010 at 8:20 PM, Hans Petter Selasky hsela...@freebsd.org wrote: On Monday 12 July 2010 19:22:28 Peer Stritzinger wrote: However the read always returns 0.

Else I recommend using LibUSB. --HPS Did'nt set this flag (not doing any ioctls on the ugen device at all). However I did try matching either the max packetlen, or the read buffer size with the actual bytes sent, so I thought it shouldn't matter. I'll move on to libusb and not waste any more time with the raw interfaces.

libusb10: libusb_bulk_transfer returns LIBUSB_ERROR_OTHER caused by USB_FS_OPEN ioctl in ugen20_tr_open
Hi,
with the setup from my post of yesterday I'm trying IN transfers with
libusb 1.0 and now I'm a bit stuck.
In essence I'm doing:
cnt = libusb_get_device_list(NULL, list);
... find device - now in found
if (found) {
libusb_device_handle *handle;
...
rv = libusb_open(found, handle);
trans_len = 0;
rv = libusb_bulk_transfer(handle, ep, buf, NBUF, trans_len, 0);
What I get is rv - LIBUSB_ERROR_OTHER to get closer to re reason for
this I debugged the last call into libusb
The error return is caused in ugen20_tr_open():
ioctl(xfer-pdev-file, USB_FS_OPEN, temp)
returns != 0, errno - EINVAL
Params to this ioctl are:
(gdb) p temp
$1 = {max_bufsize = 16384, max_frames = 1, max_packet_length = 0,

usb_desc = ugen3.2: CY7C68001 Cypress at usbus3, '\0' repeats 57 times}
BTW usb_desc is showing the right device.
Any suggestions?
Kind regards,
