Thanks all for your help. First, my digital camera works like a charm.
When I plug my GPS I have only those two lines in /var/log/syslog: Aug 30 17:23:15 zherc kernel: usb 1-2: new full speed USB device using uhci_hcd and address 4 Aug 30 17:23:15 zherc kernel: usb 1-2: configuration #1 chosen from 1 choice No /dev/ttyUSB0 Also, the module ehci_hcd is already loaded so no need to modprobe it. The output of lsusb (after the GPS has been plugged) is the following: Bus 004 Device 001: ID 0000:0000 Bus 003 Device 001: ID 0000:0000 Bus 002 Device 002: ID 046d:c506 Logitech, Inc. MX-700 Cordless Mouse Receiver Bus 002 Device 001: ID 0000:0000 Bus 001 Device 004: ID 4348:5523 Bus 001 Device 001: ID 0000:0000 By the way, this is a Garmin GPS III+ if it could help. I use a usb-to-serial adapter. Does it need a driver or something?
