I have two different devices that use a 04b4:5500 Cypress Semiconductor Chip
(HID->COM RS232 Adapter). With version 2.6.10 of Linux there were slight
issues with these devices crashing when the cable was unplugged but we could
read and communicate -- just not disconnect ;).
To support a new version of our hardware we are upgrading to the 2.6.14 kernel
but this version won't communicate with one of the devices at all and reports
'drivers/usb/serial/cypress_m8.c: cypress_serial_control - failed sending
serial line settings - -32' Both devices have the same output from lsusb.
Function that returns differently is usb_control_msg but the parameters being
passed in are the same for both versions of the kernel.
I'm cross-compiling to an arm system and using busybox.
Various logs from the 2.6.14 with debugging on
