USB: usbtmc: fix switch statment

2009-07-02T23:40:42+00:00

commit a92b63e7e4c185b4dd9e87762e2cb716e54482d0 upstream.

Steve Holland pointed out that we forgot to call break; in the switch
statment.  This probably resolves a lot of the bug reports I've gotten
for the driver lately.

Stupid me...

cdc-acm: Fix long standing abuse of tty->low_latency

2009-06-15T16:40:16+00:00

commit 7a9a65ced11ece416b730d6f21040a18e62d78a8 upstream.

ACM sets the low latency flag but calls the flip buffer routines from
IRQ context which isn't permitted (and as of 2.6.29 causes a warning
hence this one was caught)

Fortunatelt ACM doesn't need to set this flag in the first place as it
only set it to work around problems in ancient (pre tty flip rewrite)
kernels.

USB: usbtmc: add protocol 1 support

2009-03-17T21:01:28+00:00

The driver already supports the 1 protocol support, so just add it to
the MODULE_DEVICE_TABLE entry so it properly picks up these devices.

Thanks to Jouni Rynö for pointing this out.

USB: usbtmc: fix stupid bug in open()

2009-03-17T21:01:28+00:00

open() will never succeed, as we always return -ENODEV.  Fix this
obvious bug.

Thanks to Jouni Ryno for reporting it.

USB: cdc-acm: add usb id for motomagx phones

2009-02-27T22:40:50+00:00

The Motorola MOTOMAGX phones (Z6, E8, Zn5 so far) are providing
combined ACM/BLAN USB configuration. Since it has Vendor Specific
class, the corresponding drivers (cdc-acm, zaurus) can't find it just
by interface info. This patch adds usb id so the cdc-acm driver can
properly handle this combined device.

The same patch to add support for MTK gps loggers was submitted by two
different people and applied twice. Remove the redundant lines.

USB: usblp.c: add USBLP_QUIRK_BIDIR to Brother HL-1440

2009-01-28T00:15:36+00:00

My Brother HL-1440 would print one document before CUPS would stop
printing with the error "Printer not connected; will retry in 30
seconds...". I traced this down to the CUPS usb backend getting an EIO
out of usblp on the IOCNR_GET_DEVICE_ID IOCTL. Adding the
USBLP_QUIRK_BIDIR fixes the problem but is it the right solution?

output from strace /usr/lib/cups/backend/usb after printing a document
(Note: SNDCTL_DSP_SYNC == IOCNR_GET_DEVICE_ID):

before patch

open("/dev/usb/lp0", O_RDWR|O_EXCL)     = 3
ioctl(3, SNDCTL_DSP_SYNC, 0x7fff2478cef0) = -1 EIO (Input/output error)

after patch

open("/dev/usb/lp0", O_RDWR|O_EXCL)     = 3
ioctl(3, SNDCTL_DSP_SYNC, 0x7fffb8d474c0) = 0
