Tested on Boyue T62 and confirmed by others:
OTG working
only with additional powersource: keyboard, mouse, flashdrive
If OTG is used without powersource and the device is drawing too much current there is a possibility of frying the device. It happens sometime (see above link to the cable). OTG powerout is not specified on any ereader I know of, so the hardware may not be prepared to handle it.
The aforementioned Wireless Presenter is working on 2.4 GHz. That is not infrared but the same frequency traditional WLAN is broadcasted. I guess the dongle needs more power than infrared but not sure about it.
