I saw Writing raw images safely to USB sticks
On Debian though, get nada from that command :-
[$] udevadm info -a -p $(udevadm info -q path -n /dev/sdb)|grep -iE "manufacturer|product"
[$]
I was asked to put it up as a new question hence doing just that :-
I do get some output from udevadm if I use monitor command :-
[$] udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

I also get output here as well :-
[$] ls -l /dev/sdb*
brw-rw---- 1 root disk 8, 16 Jun 30 15:49 /dev/sdb
brw-rw---- 1 root disk 8, 17 Jun 30 15:49 /dev/sdb1
brw-rw---- 1 root disk 8, 18 Jun 30 15:49 /dev/sdb2
Look forward to learning how to get the manufacturer and product info. or maybe it got written over or something.
Part of the command does do something :-
[$] udevadm info -a -p $(udevadm info -q path -n /dev/sdb)
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

but the latter part gives nothing, the grep -iE "manufacturer|product" part :(
Am able to get it on lsusb :-

Was able to get the required output via lsscsi i.e. manufacturer/product i.e. Jetflash and the model number. Does anybody know more Alcor Micro Corporation ?
More interestingly though, why didn't that command work ?
