With relation to the Openwrt with WL500GP-v2 test (BCM5354 chipset), I have
obtained a BUG response. After the first secs of the test with usb-serial or
pl2303 with microcom, the system reboot.
I would like to know if the problem is in the driver (usb-uhci, usb-serial)
or if is there some chipset inconsistency with the kernel?.

+
+ This driver exists because the "normal" serial driver doesn't work too well
+ with GSM modems. Issues:
+ - data loss -- one single Receive URB is not nearly enough
+ - nonstandard flow (Option devices) control
+ - controlling the baud rate doesn't make sense
+
+ This driver is named "option" because the most common device it's
+ used for is a PC-Card (with an internal OHCI-USB interface, behind
+ which the GSM interface sits), made by Option Inc.
+
+ Some of the "one port" devices actually exhibit multiple USB instances
+ on the USB bus. This is not a bug, these ports are used for different
+ device features.
