What's wrong with lsusb | awk '{print $6}' | xargs --null lsusb -s

Command 1:

lsusb | awk '{print $6}'

Output 1:

1d6b:0002
0627:0001
0627:0001
0627:0001
0409:55aa
46f4:0001
1d6b:0003
1d6b:0002
1d6b:0003

Command 2:

lsusb | awk '{print $6}' | xargs

Output 2:

1d6b:0002 0627:0001 0627:0001 0627:0001 0409:55aa 46f4:0001 1d6b:0003 1d6b:0002 1d6b:0003

But command 3:

lsusb | awk '{print $6}' | xargs --null lsusb -s

Output 3:

Bus 001 Device 002: ID 0627:0001 Adomax Technology Co., Ltd QEMU Tablet

And command 4:

lsusb | awk '{print $6}' | xargs --null lsusb -d

Output 4:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I expect:

folkertmeeuw@fedora:~$ lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0627:0001 Adomax Technology Co., Ltd QEMU Tablet
Bus 001 Device 003: ID 0627:0001 Adomax Technology Co., Ltd QEMU Tablet
Bus 001 Device 004: ID 0627:0001 Adomax Technology Co., Ltd QEMU Tablet
Bus 001 Device 005: ID 0409:55aa NEC Corp. Hub
Bus 001 Device 006: ID 46f4:0001 QEMU QEMU USB HARDDRIVE
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Solution

Several issues:

You use xargs --null while your awk script separates the outputs with newlines, not null characters.
You use lsusb -s but you pass it vendor:product specifications, not bus:device specifications.
You should probably use the -n1 option of xargs because lsusb -s (or lsusb -d) accepts only one bus:devnum (or vendor:product) specification.

If you want to use vendor:product specifications try:

lsusb | awk '{print $6}' | xargs -n1 lsusb -d

Or, to avoid duplicate outputs:

lsusb | awk '!seen[$6]++ {print $6}' | xargs -n1 lsusb -d

If you want to use bus:device specifications try:

lsusb | awk '{sub(/:$/, "", $4); print $2 ":" $4}' | xargs -n1 lsusb -s
