Hi,
We have a problem at work where my coworkers are manually (visually)
parsing through the output of "usb-devices" to find information (bus,
vendor, prodid, manufacturer, serialnumber, etc) and then using that
information to fix problematic devices using that information. I'd like
to write a python script to accomplish what my coworkers have been doing
by hand, but instead of parsing through the output of "usb-device"
(which I could do, but it's tedious), I'd rather get that information
from pyusb if it can provide what I'm looking for. I've been searching
google and scouring through the documentation, but I'm confused and I'm
stuck. I tried the code below but it's just displaying numbers instead
of text:
import usb.core
# find USB devices
dev = usb.core.find(find_all=True)
for cfg in dev:
print('Serial Number=' + str(cfg.iSerialNumber))
print('VendorID=' + hex(cfg.idVendor))
print('Manufacturer=' + str(cfg.Manufacturer))
print('Product=' + hex(cfg.iProduct) + "\n")
and it outputs this:
Serial Number=3
VendorID=0x424
Manufacturer=1
Product=2
Serial Number=3
VendorID=0x403
Manufacturer=1
Product=2
...
Obviously that's not what I'm looking for. I'm really hoping to get
more information similar to the output from usb-devices:
T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=480 MxCh= 8
D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=01 MxPS=64 #Cfgs= 1
P: Vendor=1d6b ProdID=0002 Rev=04.04
S: Manufacturer=Linux 4.4.0-116-generic xhci-hcd
S: Product=xHCI Host Controller
S: SerialNumber=0000:00:15.0
C: #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=0mA
I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub
T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=480 MxCh= 7
D: Ver= 2.00 Cls=09(hub ) Sub=00 Prot=02 MxPS=64 #Cfgs= 1
P: Vendor=0424 ProdID=2517 Rev=00.00
S: Manufacturer=cambrionix
S: Product=U16S
C: #Ifs= 1 Cfg#= 1 Atr=e0 MxPwr=2mA
I: If#= 0 Alt= 1 #EPs= 1 Cls=09(hub ) Sub=00 Prot=02 Driver=hub
...
Any help would be much appreciated!
Thanks,
Mike
