2010-05-20usb-storage: always print quirksFelipe Contreras
Right now quirks are printed only when the are manually overriden with the module parameters. It's not so useful to remind the user that his parameters are correctly applied; what is useful is to print out the quirks the user is not aware are being applied. So let's do the smart thing and print the quirks when they are present.

2010-05-20USB: visor: increase bulk-out buffer sizeJohan Hovold
Increase the bulk-out buffer size to avoid any regression in throughput after replacing the old writing scheme which used dynamic buffers (e.g. up to 2k). 256b has been determined to be a good choice for several drivers including ftdi_sio which used to have a more or less identical write implementation.

2010-05-20USB: visor: reimplement using generic frameworkJohan Hovold
Kill custom read and write implementations (dynamically allocated write urbs). Note that I chose to remove the stat module parameter which was supposed to keep count of the amount of data sent and received, but which has been broken for three years (since b308e74d9c708ee2a9af14fbe235e0a41216f4ed "USB: visor driver adapted to new tty buffering" -- bytes_in was incorrectly updated and was thus always reported as 0).

After switching it has ID 0b3c:c000 and provides 5 serial ports ttyUSB[0-4]. Port 0 (modem) and 4 are interrupt ports.
