I should use a device with USB to serial interface by Cypress 
Semiconductor (Vendor ID: 0x04b4 and Product ID: 0x5500) on a computer 
with Scientific Linux 4.6.

The kernel that i use is 2.6.9-67 and the support for the cypress chip 
is only from kernel 2.6.10 with the module "cypress_m8".

Since I can not upgrade the kernel, is it possibile found a driver for 
that chip working under kernel 2.6.9?

This is the cat of /proc/bus/usb/devices:

Thanks.
