Hi, The sigrok Cypress FX2 / fx2lafw driver also failed to work reliably on my Intel Core i7 featuring USB 3.0 ports. In this case the USB 3.0 ports are provided by an ASmedia USB 3.0 controller (one variant of xHCI). The error is 'no room on ep ring'. I did not see this error on a Renesas/NEC-based xHCI controller on the same machine.
I'm running on debian 3.2 kernel. Backporting only the Linux 3.4 USB xHCI /hcd/hub changes was surprisingly straightforward and enabled the FX2 sampling @ 24 MHz via the ASmedia xHCI controller. Unfortunately I did see a kernel stability issue upon unplugging another USB device on this kernel, so there is some more work needed before I can publish this workaround.
