quick question..
why in version-1.0.2, the "usb_clear_halt" function is commented by the Author ?

int switchSendMessage () {
   int message_length, ret;
//   usb_clear_halt(devh, MessageEndpoint);
   SHOW_PROGRESS("Trying to send the message to endpoint 0x%02x ...\n", MessageEndpoint);

It seems that by omitting that function before write_bulk, bandluxe card C100s fail to do modeswitch. Previously, the Bandluxe C100s works just fine with ver 0.9.5, because the line "usb_clear_halt" still exist.

Why ? Is the "usb_clear_halt" have compatibility problem with other cards, so in newer version it is ommitted ?

The first clear_halt was inserted together with the second one to solve problems with the USB/udev system. It turned out that on my setup only one call - after the switch - was necessary, so in a cleanup sweep I later took it out.

Since it does not seem to interfere with my setup either, I will enable it again in the next version. If there are other devices that don't like it, I can alway make it an option.

Thanks for reporting !
