How to use a USB scanner with your HTC One M8

I know that it sounds a bit “this can’t work”, but it works. Depends a bit what scanner you’re using though (I used a Canon).

But, it depends a lot on what scanner you’re using. And, you might need a special cable for it. I just happened to have all the bits needed for it, the cable ain’t that special but you might need it. It’s just a regular UBS OTG cable adapter but with add extra usb socket for USB power so you can connect any usb charger to it.


Why? so that you can offer the USB voltage that the scanner (or other devices) might need.  This is for the scanners/etc that gets powered via the USB cable.

But, it worked for me with just a regular $1 USB OTG adapter cable as well. This with my Canon LIDE 50 scanner.


Ok, I got the cables needed. Then what?

Well, this is the most important part. You need to install an app for it. I need to stress that it might not work at ALL with the type of scanner you’ve got.

First you need to install USB scanner, this is the trial version that gives you 10 scans before it stops working. Right now the full version is reduced (which I got once I’ve tested that it works).

To get started it’s just to connect everything and start the app, you will get asked when you start it if you want to let it access USB devices. From there it’s just to press Scan, and off it goes. For me it was that simple, which I was a bit amazed over. And, it can save what you scanned to a PDF file that you can just mail or do whatever with.

And, that’s pretty much it. I’m pretty glad that this works since my scanner doesn’t have drivers for Windows 8 (which I use on my main computer).

It worked of course on my M7 as well I should mention. I think that it will work on any device that supports USB OTG, which might give my Nexus 7 some problems.


  • Glad it works for you. I’m trying to do the same with a Canon MP550 all in one device, sadly the USB Scan app that you mentioned “isn’t available in my country” yet according to the Play Store, and I haven’t found any other suitable apps yet. Do you happen to know of any or could you upload a APK of the USB scan app?

    • Assume that it will not work with one of those all-in-one devices. I haven’t tried the usb scanner app on my phone with 6.0, but do try (it’s the trial)

      • Thanks very much for the fast response and upload 🙂 Sadly I can’t get the app to work on my Galaxy S6 Edge, it shows “searching USB devices” then crashes out straight away. I’ll keep playing with it and let you know how I get on.
