Enumerating a USB device in Linux

Is there a command to enumerate the USB device (HID) programmatically or through some commands?

In Windows we can do the same using Device Manager or devcon. I tried doing rmmod and insmoding the device driver, but it didn't enumerate the device.

To see all USB devices' data:

#!/usr/bin/env python
import sys
import usb.core

# find USB devices
devices = usb.core.find(find_all=True)
# loop through devices, printing vendor and product ids in decimal and hex
for cfg in devices:
  sys.stdout.write('Decimal VendorID=' + str(cfg.idVendor) + ' & ProductID=' + str(cfg.idProduct) + '\n')
  sys.stdout.write('Hexadecimal VendorID=' + hex(cfg.idVendor) + ' & ProductID=' + hex(cfg.idProduct) + '\n\n')

Generally, USB devices are 'enumerated' internally in the kernel driver. Any time you list them with lsusb, this will show the actual devices present at that time. If you want a detailed listing of each devices, add -v (or --verbose) to the command.

Is that the information you are looking for?
