Usb to Serial converter RHEL4 not recognised
 

Can anyone advise please?

I have purchased a Dynamode USB-RS232 converter but it doesn't appear to be recognised in RHEL 4 with full updates (kernel 2.6.9-42.0.3.ELsmp). When I connect it to my laptop (FC6) it is assigned a port i.e. usbTTY0, but when connecting to a server running RHEL 4 it is recognised but not assigned a port. See below output from dmesg.

drivers/usb/serial/usb-serial.c: USB Serial support registered for Generic
usbcore: registered new driver usbserial_generic
usbcore: registered new driver usbserial
drivers/usb/serial/usb-serial.c: USB Serial Driver core v2.0
usb 4-2: USB disconnect, address 2
usb 4-2: new full speed USB device using address 3
usb 4-2: USB disconnect, address 3
usb 4-1: new full speed USB device using address 4


I thought this was initially due to missing kernel module so entered insmod usbserial and reconnected the device but with the same results. I can post lsusb and lsmod if required.

:scratch:

As root type the following
mknod /dev/usb/ttyUSB0 c 188 0
mknod /dev/usb/ttyUSB1 c 188 1
mknod /dev/usb/ttyUSB2 c 188 2
mknod /dev/usb/ttyUSB3 c 188 3

That should give you some USB to Serial port device nodes.

Tried to mknod but firstly /dev/usb directory didn't exist so created it and entered the mknod commands but same results. So removed device and usb directory, then repeated mknod commands without the usb subdirectory i.e. /dev/ttyUSB0 but still same results.

Thanks
