Is there any documentation about how to directly operate the board through the USB port? This would allow use by Raspberry Pi or other computers.

I ordered one but haven't used it yet. I do see code examples at: http://www.sainsmart.com/sainsmart-4-channel-12-v-usb-relay-board-module-controller-for-automation-robotics-1.html#customer-reviews under "Tutorial" tab. Hope this helps.

According to the documentation at the end of the description and matching my experience, the board uses an FTDI chip (FT245R USB FIFO IC) to convert between USB and the signals directly driving the relays.

The USP over IP, 1 port, is a decent appliance, but it doesn't see everything. I wanted to be able to put my Makerbot Replicator (3D printer) in another room, I thought this would make it possible. After installing the required software and connecting the USB Over IP to my Makerbot I was disappointed to find my computer could not recognize it. I tested different items to see if it was the USB Over IP or the "end" item.. I was able to successfully use the USB Over IP to connect to USB web cams, thumb drives and TV tuner cards (as an SDR appliance.) I did not try an external hard drive. I'm sorry to say, but the only answer I can give you is "I don't know." It works for some items, not for others.

No troubles here. Make sure you have the proper drivers. One thing I noticed is if you power from USB, windows may complain about the device not working at full speed. You want to power it up externally first, then plug in the USB.Mine uses an official ATMEL chip so its pretty much the same as an arduino (who's hardware design is open source ;) ). If you have issues with it connecting to the computer, power it externally first (wait for the white light) then plug in the USB cord.

There is no USB ports on the rig. There is a USB to MIC/PTT cable for programming but no for the actual function of the rig itself

That is how I learned about tke key board, reading an article about all the stuff one needs to use on a Raspberry Pi device to make it function. And the author said he had one of these keyboards for that purpose. Have fun, I really enjoy using it!

Thanks for the answers. One more question, did any of you did a new install? based on the answers it seems that most or all of you just replace an old/broken board with this one. I am actually looking to do a new installation.

I didn't have luck with it at all. Then I got a Unitek 3+1 port USB3.0 Hub, also off Amazon...super cheap powered hub and works great, no problems

I had it working on Rasbian with RetroPie installed. The device stopped working all together on any machine after 3 days though.

I'm testing it out right now, it was recognized after a reboot in emulationstation. The usb was just recognized after installing the driver from retropie_setup.sh. This is on RetroPie 2.4.2

Can you confirm if you got a solution for your problem? I have the same situation, lost the usb receiver and I'm trying to look for a replacement as well. let me know how you figured it out.

The recommended way is to use a powered USB hub. The Pi is a bit power hungry requiring up to 700 mA to operate. Many use a small cell phone charger to operate it and a lot of them are only 1 amp, which doesn't leave a lot of excess power to run the other components. If the Pi doesn't get adequate power there can be some intermittent operating problems. The answer that Noel provided below is using an external 4-port hub, which I assume has its own power supply. Spend a few $ and get a powered hub!

I would say you need the USB controller because one side is USB the other fits into the sign it self like say a phone USB plug in other words I don't see a way to plug it in without the USB. Also it changes the speed and the flashing type. Of course that can also be done with the remote control. I use mine at the Library I work at, we love it, we get comments on it all the time.

I do not know what a raspberry pi is, but it should work as long as there is a USB port.

Yes I am using it with a Raspberry Pi and HomeGenie. Surprisingly easy to get working if you download the HomeGenie sd card image

Yes, I used it on raspberry pi with no issues. You just have to download the package for it, that a quick search with Google will provide.

I haven't used it yet, bit what version are you wondering about? It should be a generic USB to serial programmer to flash PIC microcontrollers. It is a pretty simple protocol to implement.James

I would not buy this product. I was not able to get it to work with my raspberry pi. I followed the instructions on their webpage and came to the conclusion that their support was inadequate.
