Hello -
I apologize in advance if this is not the right place to ask this
question. I could not find a maintainer for the Garmin usb driver and
Documentation/usb/usb-serial.txt directed me to linux-usb.org and this
list.
I'm essentially trying to get a Garmin GPS device to load and use the
usbserial driver, but I believe the device simply is not supported. It
recognizes that there is a device there but /dev/ttyUSBx is never created.
Per the FAQ:
1. I am using the latest Fedora kernel (2.6.32.11-99.fc12.x86_64) which I
believe includes an unmodified v0.33 Garmin driver.
2. Pertinent info from /proc/bus/usb/devices:
T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#= 3 Spd=480 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=091e ProdID=239c Rev= 5.09
S: SerialNumber=0000da32c553
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=500mA
I:* If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
E: Ad=83(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
E: Ad=01(O) Atr=02(Bulk) MxPS= 512 Ivl=0ms
Notice usbstorage works just fine.
3. Output when loading garmin_gps:
Apr 13 00:56:56 localhost kernel: usbcore: registered new interface driver

Apr 13 00:56:56 localhost kernel: USB Serial support registered for generic
Apr 13 00:56:56 localhost kernel: usbcore: registered new interface driver

Apr 13 00:56:56 localhost kernel: usbcore: registered new interface driver
garmin_gps

It would take me five years to get good enough at programming to even
think about patching this. I'm not sure if there is an official place to
record feature/device requests of this nature. Any help in pushing me in
the right direction as an end-user would be greatly appreciated. I'd be
willing to help test and perhaps provide a small cash donation if
necessary. :)
Thanks!
