Return idVendor, idProduct and endpoints via lsusb-CodePudding

I want to return just some of the data of my lovely printer. (The name always contains STMicroelectronics printer

I can print out all plugged USB devices with the lsusb command. This will give me (first line obviously being the printer):

Bus 001 Device 004: ID 0483:5743 STMicroelectronics printer-80
Bus 001 Device 003: ID 0424:ec00 Microchip Technology, Inc. (formerly SMSC) SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Microchip Technology, Inc. (formerly SMSC) SMC9514 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub`

I can now find the device's details via lsusb -vvv -d 0483:5743, which returns:

Now... How can I just return these data via bash:

idVendor (0x0483)
idProduct (0x5743)
endpointOUT (0x01)
endpointIN (0x81)

There must be some grep/regex magic that I just couldn't manage to master.

Thanks for any help in advance!

Searing for solutions to extract the line containing the printer description with regex.

Suggesting the following awk script:

awk '/idVendor/||/idProduct/{printf("%s (%s)\n", $1,$2)}/bEndpointAddress/{printf("endpoint%s (%s)\n", $NF, $2)}' $(lsusb -vvv -d 0483:5743)

CodePudding user response：

Using GNU sed

$ sed -En 's/[ \t]*b?(id[vp][^ \t]*|endpoint)(address)?[ \t] ([^ \t]*).* (out|in)?.*/\l\1\4 (\3)/Ip' <(lsusb -vvv -d 0483:5743)
idVendor (0x0483)
idProduct (0x5743)
endpointOUT (0x01)
endpointIN (0x81)
