I have a cheap DVB USB dongle.
After plugging it in to linux lsusb
shows me
Bus 001 Device 004: ID 15a4:1001 Afatech Technologies, Inc. AF9015/AF9035 DVB-T stick
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
so it is an Afatech dongle model AF9035.
