Bought two different cheap USB-OTG cables from Amazon, this one
, and this one
. Only the second one has arrived.
The following USB Flash drives mounted with Stickmount and were visible to ES File Explorer.
Sandisk Cruzer 4GB Micro U3
Sandisk Cruzer 4GB
PNY Attache 256MB
The following microSD, and SD cards were inserted in Sandisk MobileMate SD+ Card Reader, mounted with Stickmount and were visible to ES File Explorer.
Sandisk microSD 16GB Class 4
Sandisk microSDHC I 16GB
Sandisk microSD 32GB Class 4
PNY Optima SD 2GB
Sandisk SD 2GB
The following two external hard drives did not mount with Stickmount when attached directly to the USB-OTG cable.
Generic EIDE case with 40GB 2 inch hard drive.
Toshiba 1TB USB3.0*
* Note the Toshiba drive partially powered up but made a clicking noise.
Connected a D-Link DSB-H4 USB Hub (USB 1.1) powered by an AC adapter to the USB-OTG cable. Then connected the two previous external hard drives to the USB hub and was able to mount both external drives, at the same time, with Stickmount and both drives were visible to ES File Explorer.
A couple of times ES File Explorer failed to read any files on the microSD cards even though Stickmount indicated the card was mounted. When I went into Stickmount and select Mount then the microSD card contents would be visible to ES File Explorer.
Both a USB keyboard and USB mouse when connected directly to the USB-OTG cable did not work.
However, using the aforementioned AC powered D-Link USB Hub connected to the USB-OTG cable, both the USB mouse and USB keyboard worked on the Nexus 7.
