That can't be right.ok, lets say i get the hub that splits into 4 usb's. the question becomes, if i split the single micro usb port on this tablet, can i send voltage (a charging voltage, current) back through the tablets usb port? all the while having a dna 200 or any device that requires the usb 5 volts charge, operate. simplified, can a single micro usb port send and receive voltage? (voltage out for a device and voltage in to charge the tablet, all at the same time.) as for soldering on a second micro or full size usb on the mother board i guess it would be possible. theres no extra room on the board for a second so i would have to piggy back it off of the original. but if i do that, i would in effect bypass escribe's commands for both analyzers. im sure you know when running batt analyzer you have to turn the charging current to zero in device monitor so the mods battery doesn't charge in between firings. and case analyzer intermittently turns the charge on and off and also sets specific current limits at certain points in the test. believe me, i've racked my brain or this and i think ive got a decent solution. just gonna hot glue one of the micro usb charging boards(5, 1 amp boards for $3 from ebay #TP4056) to the bottom of this tablet or if im feeling frisky, find room inside the tablet casing, install it internally and make it look nice.
edit.....to sum it up, the charge needs to come from the tablet, through escribe, when running any of the two analyzers. can't come from usb hub.
Escribe setting charging current to zero tells the dna200 not to accept power from the USB from the Laptop. It does not tell the laptop to stop delivering power. At least I think that's the case.
Right?
