Post by Vlad » Sun Jan 06, 2019 10:54 am

Hi! Help me please.
I have fulcol K900 android 6.0 chineese tablet.
USB host mode it havent default, so i install root rights and include "android.hardware.usb.host.xml" file at /system/etc/permissions

OTG Test For RF Explorer program shows that USB host mode work sucessfully.

I chacked my RTLSDR it Windows 7 and samsung g5 (a 8.0) works ok.

I install RTL SDR drivers and SDR Touch at K900 (a 6.0) tablet.
SDR don't work. USB voltage 5.15V. SDR driver program don't see SDR and write "0 device foud"
SDR Touch say "No device found, check voltage or you haven't USB host mode".

Is that 5.15V without any load? The RTL-SDR might be putting too much load on the tablet, reducing the voltage too far. Can you try with an OTG cable that has an external power port?
