I'm working on getting a Galaxy Tab 10.1 to communicate with a PIC via USB, with some success - I had the tab and PIC communicating with no problems and was starting to work on getting serial messages transferred.  I'd also written a generic routine that could list all connected devices.
Then last week I "upgraded" to Tab to an official version 4.0.4 via Kies.  Now the USB link in the tablet seems only to recognise some types of accessory - it will see USB mass storage, but not a mouse, for instance (the mouse is there and moves the cursor OK, but my software cannot detect it.)
I have seen some posts from some time ago regarding Samsung restricting the types of USB device that the tab could use, but had my software working quite generically with no such limitations apparent.

Anyone got any ideas for a fix?  failing that, any suggestions as to how to get rid of the upgrade?

Current version is Android 4.0.4
Kernel version:
3.1.10-1174051

Update - after discussing with Samsung support, it seems they will downgrade to 4.0.3 for a fee, as an out of warranty action.
I have managed to get the Tab to recognise the PIC by using the Mass Storage class code in the PIC configuration - so it seems that the Samsung will let Android access the USB hosting functions only for mass storage devices.

How much are they charging to downgrade it? Will they still honour your warranty for any future claims or is it going to be void in general?

The reason I ask is because it is relatively easy to downgrade the firmware yourself with the right tools (Odin and the relevant firmware package)

Thanks for the reply.

Cost of the downgrade is $45. (+ gst). I also have to go through my original supplier (Warehouse Stationery) who may want proof of purchase - not sure I can find the original sales document.

However, I'd prefer to use their "services" at the moment as I want to get on with the other parts of the project and not have to faff around with learning new tricks with Android.  Setting up my PIC hardware as a memory device seems to work (so far).
