Fedora7 USB GPS problem



Hello-
Having a problem getting a DeLORME USB GPS LT-20 device working with my Fedora 7 laptop. It is supposed to work with the cypress_m8 serial module.

when I loaded the module and plugged in the device, it created the device (a ls -l in /dev shows this: crw-rw---- 1 root uucp 188, 0 2007-11-18 22:24 /dev/ttyUSB0). it shows up when I do a 'cat /proc/bus/usb/devices':
T:  Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  5 Spd=12  MxCh= 0
D:  Ver= 1.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=1163 ProdID=0200 Rev= 0.01
S:  Manufacturer=DeLorme Publishing
S: Product=DeLorme USB Earthmate C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=100mA
I:* If#= 0 Alt= 0 #EPs= 2 Cls=03(HID  ) Sub=00 Prot=00 Driver=cypress
E:  Ad=81(I) Atr=03(Int.) MxPS=  32 Ivl=6ms
E:  Ad=02(O) Atr=03(Int.) MxPS=  32 Ivl=6ms


when I do a 'cat /dev/ttyUSB0' I get basically nothing as output. Some Internet searching tells me to comment out line 408 (that haas the code 'cypress_set_dead(port);') in the cypress_m8.c file and recompile the module. At this point I am stuck. I found the file and there is the appropriate line at position 408, I can comment it out but do not need to know what to do to recompile this module.

Any assistance would be greatly appreciated!
