This question is an exact duplicate of:

I have a HCL ME U1 tablet. This has a built in USB Type A socket as well as USB Mini Type B socket. I have tested the Type A socket with a standard mouse and it works well. I have also tested it with a GSM 3G dongle and that too is working well. Thus, I believe this shows that the tablet has complete support for USB Host functionality.

However, when I run the USB Host diagnostics tool. It does not detect insertion of any USB device!

My basic aim is to connect an Arduino/Freeduino (which is using Silicon Laboratories CP2102 USB to Serial Converter chip)

I tried various libraries to access these devices, USB Serial Library. However, none of them work ... What do I need to do to access these Arduino devices? Will just rooting the tablet help? Does something else have to be done?

  • And what android version does your tablet have – cde Dec 17 '14 at 19:09
  • What's really important is that OP Pankaj21 already asked this question HERE on android stack before posting it on EE. Thus there are now two duplicate posts here. Flagging for deletion now. – Bort Dec 18 '14 at 0:49
  • This question definitely has to do with Android. OP wants to be able to hook Arduino to a Android tablet. So the question is valid........As to being a duplicate, most certainly is. – HasH_BrowN Dec 18 '14 at 6:57
  • Which is no reason to post it twice (see the duplicate Bort found). // Pankaj: This post here got migrated from another site. As crossposting is not welcome at SE sites, this is the way topics are "moved" here – not re-posting. Exceptions might be cases where the target site requires a completely different phrasing; but in those cases, the original question should not be migrated. Always chose one path only, please ;) – Izzy Dec 18 '14 at 9:57
