Question: Will this connect a tablet case that has a keyboard?
Document: I purchase this cable for my office samsung galaxy tab 3 8 inches. I use this cable to connect to the tablet mainly for packages scanning. It works as described.
we bought this to use with the Samsung galaxy note 10.1 2014 edition tablet. works great, nice and compact, easy to store
There are several ways to transfer data from a PC to Tablet etc. This adapter gives you quick & simple way to transfer large amounts of data and is handy if your don't have access to the other methods.
This adapter is good because it can connect regular portable hard drives. The other off-brand USB adapter doesn't work as good. I tested this on USB memory stick, memory card reader and portable hard drive. They all work. Great buy.
Works great with the Samsung Galaxy Tab Pro. My only complaint is that you have to use this expensive proprietary adapter rather than a cheaper generic MHL adapter. The whole reason I use Androids is so I don't get stuck with proprietary equipment requirements.
Works great for everything, bought it for my Samsung Galaxy Note 10.1 2014 edition, use it for instant connection to printers, flash drives, my voice recorder, my cell phone, EVERYTHING. Has been plug and play for every single thing I've tried. Verify the number of pins your samsung device has on its micro-usb port before purchasing or you may need another model or an adaptor
Works as described. Great Service from Nu Image (U.S.P.S. ), travelled across the pond faster than something ordered from half way across my own country. Wouldn't hesitate to order from them again.The only advice I would give to Nu Image is if possible post inside padded bag as card was badly ripped either by customs or wear and tear. Item would have been easily stolen or dropped out of package.
USB data transfer adapter works great. I use it to watch movies from my flash drive or external drive. Also, UPS lost my order, but Nu-Image resend another one right away.
This was exactly what I was looking for to use with my Samsung Tab 3 10.1, and found out that I can also use it on my Samsung Galaxy S3.
This was a gift
Answer: I bought the USB dongle for my Tab 3 and I've used it for USB jump-drives, my camera, my phone to share the data, and just cause you asked and I wanted to know. Why yes it does work with a USB keyboard. You might want to consider getting a small bluetooth keyboard just for ease. That's what I normally use with my tablet, but the USB keyboard works just as well with the dongle.
