Bug#293704: usbserial and ircomm don't work on sparc
This is actually 2 separate problems with Debian kernel-source on sparc.
The ircomm causes a hard lock with irda-usb on both sparc64 and powerpc.
The other problem is usbserial does not work on sparc64, but I have
pl2303 working on powerpc. pl2303 half works on sparc64. visor does
not work on either sparc64 or powerpc.
When I test ircomm on powerpc via usbserial I get lots of packets, but
no serial data passed, however it possible to shut the machine down
