I'd like to be able to identify the chipset a particular USB device is using. I know about lsusb (and now /proc/bus/usb/devices), but they don't provide as much information as lspci.
Here is an example of how I use lsusb:
(laptop:/proc/bus/usb) # lsusb -v -d 050d:805c Bus 001 Device 008: ID 050d:805c Belkin Components Device Descriptor: : idVendor 0x050d Belkin Components idProduct 0x805c bcdDevice 0.01 iManufacturer 1 Ralink iProduct 2 802.11 n WLAN :
… and /proc/bus/usb/devices (thanks to a comment on this thread):
T: Bus=01 Lev=02 Prnt=03 Port=02 Cnt=01 Dev#= 8 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=050d ProdID=805c Rev= 0.01 S: Manufacturer=Ralink S: Product=802.11 n WLAN C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr= 4mA
Although I can see that I'm looking at the right USB device (Belkin USB 801.11n with Ralink chipset), I still can't determine the exact chipset version. The "0x805c" doesn't match a chipset number I'd expect ( 2500 – 2900 ).
I'm thinking that perhaps it isn't even possible to query this information across the usb bus?
Thanks in advance for any help.
