Yes, One of my OTG Cables has gone intermittent too. I think these things are made in cottage industries and that would explain the price which is often less than the postage stamps on the packet.

I've put one of my TPs into Android, and got interesting msgs. Please confirm this is 'right' operation in android 'settings->about tablet->status' Battery Status is 'charging (USB)' if I use standard HP cable into a desktop USB port. Battery Status is 'charging (AC)' if I use HP barrel PSU. So far so good. If I put one of my prebought, supposedly OTG cables, or the fixed up unitary adapters in the TP, then run it to the desktop USB, the Battery Status is 'discharging' no matter what cable combo I try. You mentioned earlier in PrivMsg that an OTG with 4-5 shorted won't allow charge mode. Does seeing 'discharging' in android imply that my OTG cable is indeed in correct mode for TP to see a kb/usb stick?
This is a Looooong answer but in a nutshell, the charging current (within the limits of the ability of the source to provide it) is controlled by the state of the Data+ and Data- lines. See my posts on this subject in this thread http://forums.precentral.net/hp-touc...ouchpad-6.html
Also, maybe this means I've misread the WebOS msg, but when i get the 'USB Drive' or 'Just Charge' msg, and pick Just Charge, the battery will go down while connected to my desktop. I was assuming HP really meant if you want to charge, use the charger.. BUT, in android mode, I've simultaneously got a working USB mass storage device, AND battery status says 'Charging (USB)' and the battery level has not gone down in two hours. Do you know if HP/WebOS just disables the charging circuit when in USB Drive mode.
.... makes it worth the effort if it does
Sorry to ask so many questions, but I'm sure your answers will help everyone.
Thanks much Wheel_nut
