I'm on my 3rd tablet. I just flat wore out the first one, the 2nd one still works but has no hdmi port (for displaying on larger screens), and now I find that my latest tablet (agptek) has only one port (female micro-usb) for both charging and usb connection.
In the past I have used the micro-usb port for a footswitch while having power connected through a separate power port. I started looking for a replacement but this seems to be the current trend in 7" tablets. Samsung, et-al are moving to a single micro-usb port for charging like cell phones.
According to the usb spec there should be a device, referred to as an "accessory charger adapter" that would allow you to both charge and use a usb device simultaneously on the same port but apparently nobody makes one.
btw, none of my tablets has bluetooth, thus the usb footswitch (more on this in another thread).
Anyone else having this problem?
I don't know if this helps, but some materials I have read said its probably not a good idea to charge while you are using the tbalet anyway (its good to let the battery wear down to, let's say, 50% before charging).
So, a simple resolution is just to unplug the charger when you are using tablet and put the charging usb back in when you are not using it (I guess that's what you are doing now).
