[sane-devel] *** GMX Spamverdacht *** What same USB device ID means

[abel deuring]

USB product IDs by themselves give not clue at all what the type of a
device is or might be. Have a look here:

http://www.linux-usb.org/usb.ids

While the product IDs you found for Kyocera MFPs do not appear
frequently, search for example for the product ID 0201: I'm seeing

- a UMTS modem from TP-Link,
- a scanner from HP,
- a hub from NXP/Philips,
- a USB/IDE adapter from I-O Data,
- a "monitor hub (whatever that might be...) from Iiyama,
- a "gaming keyboard" from Chicony Electronics,
- a touchscreen from Elan Microeletronics
- an RS232 adapter from Sunplus
- a "peripheral switch" from Belkin

...then I gave up looking for more devices with the product ID 0201 ;)

In short: Only the combination of vendor ID and product ID is supposed
to tell you if a device is a scanner / mouse / camery or whatever else.
