Wow, I thought the kernel synthesized modalias fields for all hardware it knew about, and have never seen any USB unit where the kernel did not provide a modalias file. > What does `udevadm info` say about the device? For my test unit I get this: P: /devices/pci0000:00/0000:00:1a.0/usb1/1-1 N: bus/usb/001/000 E: BUSNUM=001 E: DEVNAME=/dev/bus/usb/001/000 E: DEVNUM=000 E: DEVPATH=/devices/pci0000:00/0000:00:1a.0/usb1/1-1 E: DEVTYPE=usb_device E: DRIVER=usb E: ID_BUS=usb E: ID_MODEL=Tenx_Nonstandard_Devic E: ID_MODEL_ENC=Tenx\x20Nonstandard\x20Devic E: ID_MODEL_FROM_DATABASE=Rocket Launcher E: ID_MODEL_ID=0202 E: ID_REVISION=0100 E: ID_SERIAL=1130_Tenx_Nonstandard_Devic E: ID_USB_INTERFACES=:030000: E: ID_VENDOR=1130 E: ID_VENDOR_ENC=1130 E: ID_VENDOR_FROM_DATABASE=Tenx Technology, Inc.

I'm testing using my USB Rocket Launcher to use USB unit that is not handled by any of the packages I need to have installed on my machine. -- Happy hacking Petter Reinholdtsen _______________________________________________ Pkg-systemd-maintainers mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-systemd-maintainers
