Why does my screen display an unknown device after I plug in the USB ROCKEY4?

It may be caused by interference or bad contact points. Try unplugging the device and then plugging it in again. It is possible that the USB support option inside the BIOS has been disabled. You can enable USB support in the CMOS functions menu when your computer is booting up. Although the file RYDLL32.DLL is under the same directory as the program, FoxPro and VB programs will only search for DLLs under the system directory, so you should copy the file RYDLL32.DLL into the system directory.

Why does my USB device seem so slow?

UT Physics Linux FAQ
It might seem that the USB device is fairly slow, especially when writing to the device. This is for two reasons: Firstly, USB devices are substantially slower than hard drives or other high-speed media; furthermore, larger-capacity flash memory devices are often slower for write access than low-capacity devices. Secondly, we mount the device in "synchronous" mode, which makes writes seem slower than the more common "asynchronous" mode.

I am hearing noises when I plug my AC/USB Boostaroo into my PC. Is my unit defective?

Frequently Asked Boostaroo Questions
The answer is no, your AC/USB Boostaroo isn't defective. What you are hearing is the transient noise that your PC produces naturally through oscillation of your power supply and the hard drive whine caused by its mechanical spin. These noises are much more common in older PC's, but a lot of newer PC's have noise filters built into the PC's USB ports, which eliminates these noises. If this problem is occurring, we recommend using the AC power supply for your Boostaroo instead of the USB cable.

Can I configure more than one device per device screen?

faq's section
Yes, you can map multiple devices to the same device layer. This can be very useful; for example, if you wish to control the TV's volume using your amplifier, without having to change between the two device screens. In this case, you learn the regular TV functions from the TV remote, but the volume functions from your amplifier remote. In some rare cases, if you assign too many different remotes to the same device layer, this might fail, although no corruption of data or other damage will occur.
