U-Blox GPS cdc_acm USB Device not 'Talking'
Hello. Long time reader, first time poster.:)
My plans are to load an open distro onto a box that is currently running WindRiver 3.0. I'm successful with all hardware except I've run into a brick wall with a U-Blox GPS device. It shows up in dmesg as connected; heck, I even get a /dev/gps0 link to /dev/ttyACM0. But, upon 'cat'ing I get zero output (it does stay open as if it is working waiting for an EOF). I've tried every step the manufacturer suggests in the chip's troubleshooting. (www(dot)u-blox(dot)com/images/downloads/Product_Docs/USB_with_LINUX(GPS.G4-CS-07059).pdf Check Section 3.2) I even tried blacklisting 'cdc_acm' driver to force the 'usbserial' to load without any luck.
The device works fine running the copy of WindRiver, but no matter which distro (various kernels between 2.6 and 3.13 attempted. All the same results.) I try I keep coming up blank. Searching for any help with this sucker.
Attached is the lsusb output. (same on all distros)
Thanks ahead for any help!
