1. Usb Root Hub 3.0 Driver

For anyone who has a problem with the LimeSDR Mini not working with OS-X, perhaps this might help:. When connecting my LimeSDR Mini to my mac, the FTDI controller on the LimeSDR was not registering at all - literally. The device was getting power, but the LEDs denoted a problem. Running the command: ioreg -p IOUSB, showed the following: ±o Root ±o AppleUSBXHCI Root Hub Simulation@14000000 ±o Bluetooth USB Host Controller@14300000 ±o Apple Internal Keyboard / Trackpad@14400000 This meant that the FTDI controller wasn’t even being recognized as a USB device on the Mac’s Root Hub. Clearly then, no software will work to connect to the LimeSDR Mini (it simply doesn’t exist to the OS). I then connect the LimeSDR Mini to a USB 3 or 2.0 Hub, then connect the Hub to my mac.

Usb Root Hub 3.0 Driver

The LimeSDR Mini got power. I run: ioreg -p IOUSB and get the following: ±o Root ±o AppleUSBXHCI Root Hub Simulation@14000000 ±o Bluetooth USB Host Controller@14300000 ±o Apple Internal Keyboard / Trackpad@14400000 ±o USB3.0 Hub @14500000 ±o USB2.0 Hub @14100000 ±o LimeSDR Mini@14130000. The SDR software now works - I can even run HDSDR in a Parallels Windows VM and use the LimeSDR Mini. So if you have the same problem that I did with your mac - that the device isn’t even being recognized by the machine, then please give the USB Hub trick a try.

It seems us Mac OSX users are in the distinct minority here. I received my LimeSDR Mini back in July and while it appears to function pretty well, it has this problem where on the first run (osmocomfft -s 10e6 -a driver=“driver=lime,soapy=0”) everything works as expected but on the second run the Mini is still detected but receives no samples. This essentially forces me to continually unplug and plug each time I run a program. I’ve also had an issue where usb 3.0 operation is very noisy until I wrap my hand the board (shielding, grounding?).

Oddly, USB 2.0 mode seems to not have this problem. Have you had any of these problems?

I have a new (May 2017) desktop PC running latest Windows 10 vn1703 with 2 USB 3.0 ports on the front and 4 USB 2.0 ports on the back. Device Manager only lists USB 3.0, i.e.

One 'USB 3.0 eXtensible host controller' and one 'USB Root Hub (3.0)'. Should there be any controller or root hub for USB 2.0?? I have read that USB 2.0/3.0 should be upwards and downwards compatible and yes, the keyboard, mouse and various memory sticks work in all the ports. However I have a USB 2.0 device (a Satmap) which will not work on this machine in any of the ports. It works fine on an older machine that has only USB 2.0 ports (and therefore controllers) running Windows 10 vn1607. On the new machine, Device Manager knows the Satmap is connected (lists as USB Mass Storage Device under USB controllers, as USB Device under Disk Drives and also under Portable Devices) but nothing else can 'see' it - neither File Explorer nor the Satmap application software.

Running Troubleshooter (when it is already plugged in to a USB 2.0 port) just returns the message 'USB Mass Storage Device can't work properly with USB 3.0. If the USB 2.0 device is incompatible with USB 3.0, plugging it into a USB 2.0 port can solve the problem.'

Having read through various USB threads, I have tried uninstalling everything under USB controllers but that made no difference. Any thoughts on what to try next will be gratefully received.

Most USB 3.0 ports will work with USB 2.0 devices but shouldn't the other way around. Older hardware is seldom forward compatible with new hardware.

My latest computer shows a Generic USB Hub for the USB 2.0 ports on the back and a USB Root Hub (USB 3.0) for the rear and front USB 3.0 ports. USB 3.0 software should be included with the computer, USB 2.0 is usually supported in the BIOS for use by the keyboard during bootup.

If the software isn't contained within Windows you should have gotten a CD from the manufacturer of the motherboard or the vendor of the computer to install the drivers.

USB 2.0 may not be shown in the BIOS as such, may be Legacy USB with is needed to allow a USB keyboard necessary to make changes. Have seen older computers need a PS/2-attached keyboard to make changes before a USB keyboard can be used. Haven't seen a computer yet that has BIOS support for USB 3.0, usually gets that when the Operating System is installed and drivers installed.
