Hello,
I have the Cyclops Joule 2.0 GPS, a device for logging my bicycle rides. The device has probably a serial output and uses the FTDI drivers to connect via usb to my pc. The device
used to work fine in Windows 7 and Windows 8, but I could not make it work under Fedora.
For that reason, I installed manually the FTDI drivers shown here
http://www.ftdichip.com/Drivers/D2XX.htm and used some sort of
read/write commands packaged with the drivers (found in the EEPROM folder) to see if I can connect to my device. I could perform a read and get information of the device like manufacturer, model, deviceId, etc. This was also obvious after running
I then used some
write commands as well (also coming with ftdi drivers) but the device would not respond. I believe this was the beginning of my problems...
Anyhow, I thought then to install another distro and give it a try. In Mint Cinnamon the device was not even appearing under ttyUSB0 and dmesg is not giving any ftdi_sio - related information. Instead I get:
[11949.240838] usb 2-1.4: new full-speed USB device number 9 using ehci-pci
[11949.312811] usb 2-1.4: device descriptor read/64, error -32

[11950.976919] usb 2-1-port4: unable to enumerate USB device
I switched once again to my Windows PCs and now it's impossible to connect the device either (where it used to work). The device appears as an unknown device and I can get no descriptors. I somehow feel that due to this write operation I did with the FTDI drivers I messed up my device's descriptors. Any diagnostics coming through your head? Ideas?
I run
Mint 18 Cinnamon 64-bit (3.0.7)
Kernel: 4.4.0-31-generic
Thanks & regards
