Many USB devices contain a unique serial number (which is actually a Unicode string) which the host can use in conjunction with the 16-bit vendor and product ID numbers to uniquely identify the device.I'm trying to figure out how to write a Windows application that would be able to display a list of all USB human interface devices attached to the system. The list would have one row for each HID, including system keyboards.

There would be columns in the list for the vendor ID, product ID, and serial number.I can get a list of USB HIDs by calling SetupDiGetClassDevs with the GUID returned by HidDGetHidGuid and looping through the result by repeatedly calling SetupDiEnumDeviceInterfaces. I can then call SetupDiGetDeviceInterfaceDetail to get the path to each device, which I can open with CreateFile, so long as I am careful to request neither read nor write permission, which would be denied for a system keyboard. From there I can get the vendor and product ID numbers by invoking HidDGetAttributes.What I'm having trouble figuring out is how to retrieve the serial number string. When I search for solutions to this problem, I find a lot of information about how to get serial numbers for USB mass storage devices, but nothing that looks like it might apply to any other type of USB device. I would be happy to discover either a generic method or a HID-specific method of retrieving the serial number string.I have a feeling that the Win32 port of libusb could manage this without too much trouble, but unfortunately I need a solution that depends only on libraries that come with Windows, such as the setupapi and hid DLLs that contain the functions mentioned above.Any suggestions would be very much appreciated!

The push-buttons are used also for manually setting up a matrix connection to the test specimen and as a keyboard for preparing new tapes. TAPE READER: A block reader is used. FIXED DATA: A series of arbitrary numbers for identifying lot number, date, serial number, etc. On the logged data. SCANNER: This serves as.

• Check your Apple warranty status. Enter a serial number to review your eligibility for support and extended coverage.
• PassMark KeyboardTest™ allows users to quickly check that all the keys on their computer keyboard are functioning correctly, check the keyboard LED's, look a.

It turns out that HID.dll defines a function called HidDGetSerialNumberString that does exactly what I want, given the handle I got from CreateFile as described above. Just tried it out and it works great. There are also HidDGetManufacturerString and HidDGetProductString functions to retrieve the other string descriptors referred to in the device descriptor, and even a HidDGetIndexedString to get an arbitrary string descriptor given its index (presumably because the HID descriptor is allowed to contain string descriptor indices). I feel pretty silly now - the answer was right there under my nose this whole time.Thank you all for taking the time to read and answer my question! I'm going to go ahead and accept Alphaneo's answer since it sounds quite promising, and in fact I was waiting for the DDK to download when I stumbled across this answer. Have you tried searching for the documentation of the HID definition of input records, output records and features records for Hid keyboards.

This should show you the list of 'things' you can get out/in of a keyboard through HID.Also, I know it is possible to enumerate the HID record definition by software. I did something similar about 1 year ago, but I cannot remember the details at the top of my head. Doing so would allow you to see what the keyboard USB class is publishing as a standard interface.I hope it can get you a few pointers to find out what you are looking for. Sorry I could not be more precise!

Hi everyone,Had a weird situation where a Smart Keyboard I ordered from a reputable retailer arrived unsealed and in the wrong box. Before returning it I thought I'd check the serial number.I've seen about 10 9.7' Smart Keyboards - mostly in stores, but also family and friends - and all have a serial number starting FTP.This one, though, starts DLX. See picture.Additionally, it comes up as invalid in the Apple database. I've tried different numbers (the fourth character looks like it could be an R, P, or B) but all come up as invalid.This isn't an issue per se - I'm returning it anyway - but this is the sort of thing a nerd like me enjoys getting to the bottom of!Anyone else here have a 9.7' Smart Keyboard with a serial starting DLX?Image removed as issue resolved.

I've tried different numbers (the fourth character looks like it could be an R, P, or B) but all come up as invalid.This isn't an issue per se - I'm returning it anyway - but this is the sort of thing a nerd like me enjoys getting to the bottom of!Anyone else here have a 9.7' Smart Keyboard with a serial starting DLX? I've looked at eight display units at three stores, and four retail units from different retailers and different batches (i.e. Ones friends and family have bought). All start FT.I'm not worried, I'm just curious as to why the serial is invalid.I've removed 'stolen' from my list of possibilities (e.g. Stolen from a store) because I checked a store unit's serial on the Apple site and it comes up as valid, but without a validated purchase date, and thus no warranty (as would be expected).

My one comes up as totally unrecognised. It's not a clone. I've got it here side-by-side with one I know is genuine. They are identical in every way.If there were clones floating about then I would not be the only one to have one!

And it wouldn't have come from a big-box retailer.Not to mention that no non-MFi manufacturers have managed to utilise the Smart Connector yet.I think it's just an early pre-production unit (it was manufactured two weeks earlier than any other I've seen according to chipmunk.nl) that snuck into a retail shipment by accident.
