Getting a serial number from a usb flash stick

[carlblanchard]

Hey All

The provider of our usb memory sticks very kindly gave us the software to pre-program the memory sticks with serial numbers, How do i go about reading this serial number in vb.net winform application


Thanks in advance Carl

Well, I imagine those appear the same as a drive to the .Net framework, so if you know how to get a serial number from a hard drive, the same may apply to flash sticks.

no ive already done that, and the serial numbers are different.

ive seen a vb6 program that is ment to show the serial number via HID (HUMAN INTERFACE DEVICE) programming but it dosnt work on my win xp box for some reason....

Damn USB Stick manufacturers.... can't follow protocol can they..

[carlblanchard]

well i think they are but i dont know....

all i know is that the serial is 16 digits long alpha nurmeric

if it is a HID device, you can use this:

to read the serial # or get its PID and VID.

then probably because you used a wrong PID and VID.

ok heres the problem

in windows 2000 the device is reconised as USB Device (HID)
in windows xp its reconised as a hard drive (not hid)

this is confirmed because the software the manufactor gave us for programming the serial numbers and drive names etc etc

so is there a way to read the hardware serial number of disk drives ? the serial is a 16 digit number, ive tried using Management.ManagementClass("Win32_LogicalDisk")

but that dosnt return the 16 digit number im after
