Hi all guys, I have an irritating problem about the use of OTG performance. I have bought usb3.0 hub SDXC SDHC SD card reader combo with OTG adapter last week. I once got it working with my Samsung Galaxy Tab and Nexus 5. All things went smooth. But when my brother plugged the OTG interface into his tablet Nexus 7, his tablet started to read the data on my micro SD card slowly.( 4~6 MB/s ). More seriously, before all done, the tablet suddenly shut down automatically. We tried a few times with the same results. Also it seems not complete data can be read.
Never had I encountered such an issue. Is it related with the storage volume of devices or others? Was anybody once faced with the same puzzle? Any idea is preferred.
