Getting libusb error in ubuntu while trying to run 2 Kinects

I'm trying to run two Kinects v2 on the same machine (using libfreenect2 for ubuntu 14.04). The one is connected to motherboard USB3 host, and the other to PCI-E NEC host. Both work fine separately, but if I run one and then run another while the first is running, I get the following error for the second kinect: 

[Error] [protocol::CommandTransaction] bulk transfer failed! libusb error -1: LIBUSB_ERROR_IO

I know that it is possible to run multiple kinects on the same machine, but can't figure out what causes this error. I also tried some other hosts that didn't help. Does anyone know how to fix it?

Thanks!

Solved the problem: need to allocate bigger memory buffer to usbfx, and don't do that using 

sudo modprobe usbcore usbfs_memory_mb=64

Rather better do it by correcting the grub file (more here: https://www.ptgrey.com/tan/10685).
