Using non default baud rate fedora 12

[Peter111]

Hello,

I'm using an ftdi bridge chip, where I need to set the baudrate to 250k baud. I'm writing a program in C++ using the boost C++ librarys, every time i try to set the devices baud rate to anything other than the standard values an exception is thrown. I'm running fedora 12 and have printed the log bellow from when the device is plugged in.

kernel: usb 6-2: new full speed USB device using uhci_hcd and address 10
kernel: usb 6-2: New USB device found, idVendor=0403, idProduct=6001
