2008-05-20USB: serial: ch341: New VID/PID for CH341 USB-serialMichael F. Robbins
Recent USB-serial devices using the WinChipHead CH340/CH341 chipset are being shipped with a new vendor/product ID code pair, but an otherwise identical device. (This is confirmed by looking at INF for the included Windows driver.) Patch is tested and working, both with new and old devices. Signed-off-by: Michael F.

2008-05-20USB: add TELIT HDSPA UC864-E modem to option driverGreg Kroah-Hartman
This adds the Telit UC864-E HDSPA modem support to the option driver. This lets their customers comply with the GPL instead of having to use a binary driver from the manufacturer.

2008-05-14USB: do not handle device 1410:5010 in 'option' driverEugeniy Meshcheryakov
This device is not a serial port, but a virtual CD-ROM device. For example with my Novatel MC950D: lsusb -v -d 1410:5010 | grep InterfaceClass bInterfaceClass 8 Mass Storage After some time (ca. 5min) or if virtual CD is ejected, device id changes to 1410:4400: % lsusb -v -d 1410:4400 | grep InterfaceClass bInterfaceClass 255 Vendor Specific Class bInterfaceClass 255 Vendor Specific Class Variable name says that 0x5010 is a Novatel U727, but searching in internet shows, that this device also provides virtual CD that should be ejected before use.

2008-05-08fix irq flags for iuu_phoenix.cSteven Rostedt
The file drivers/usb/serial/iuu_phoenix.c uses "int" for flags. This can cause hard to find bugs on some architectures. This patch converts the flags to use "long" instead. This bug was discovered by doing an allyesconfig make on the -rt kernel where checks are done to ensure all flags are of size sizeof(long).

2008-04-24USB: cypress_m8: Limit baud rate to <=4800 for USB low speed devicesMike Isely
The cypress app note for the M8 states that for the USB low speed version of the part, throughput is effectively limited to 800 bytes/sec. So if we were to try a faster baud rate in such cases then we risk overrun errors on receive. Best to just identify this case and limit the rate to 4800 baud or less (by ignoring any request to set a faster rate). The old baud rate setting code was somewhat fragile; this change also hopefully makes it easier in the future to better checking / limiting.

2008-04-24USB: cypress_m8: Get rid of pointless NULL checkMike Isely
Remove a NULL check in cypress_m8; the check is useless in this context because it is referenced earlier in the same code path thus the kernel would be oops'ed before reaching this point anyway. (And it's really pointless here anyway; if this pointer somehow is NULL the driver is going to have serious problems in many other places.)

2008-04-24USB: cypress_m8: Don't issue GET_CONFIG for certain devicesMike Isely
Earthmate LT-20 devices (both "old" and "new" versions) can't tolerate a GET_CONFIG command. The original Earthmate has no trouble with this. Presumably other non-Earthmate devices are still OK as well. This change disables the use of GET_CONFIG for cases where it is known not to work.

2008-04-24USB: cypress_m8: Packet format is separate from characteristic sizeMike Isely
cypress_m8: Packet format is separate from characteristic size The Cypress app note states that when using an 8 byte packet buffer size that the packet format is modified (to be more compact). However I have since discovered that newer DeLorme Earthmate LT-20 devices (those that are low speed USB with 8 byte packet size) STILL use the format that is really supposed to correspond to 32 byte packets. Further confusing things is the subsequent discovery that there are actually two different types of LT-20 - older LT-20's use 32 byte packets which is probably why this issue wasn't originally encountered. The solution here is to flag the packet format separately from the buffer size. Then at initialization time, identify the correct combination and set it up. This is a critical fix for anyone with a newer LT-20. Older devices and non-Earthmate devices should remain unaffected by this change. (If other devices behave in this, uh, unexpected manner, it's now just a simple 1 line change to fix them as well (change the pkt_fmt member for that device). Default behavior with this patch is still to drive the format as per the app-note; of course for Earthmate devices this is overridden.

cypress_m8: Feature buffer fixes From: Mike Isely <isely@pobox.com> Don't hardcode the feature buffer size; use sizeof() instead. That way we can easily specify the size in a single spot. Speaking of the feature buffer size, the Cypress app note (and further testing with a DeLorme Earthmate) suggests that this size should be 5 not 8 bytes.
