在龙芯2K1000上使用linux3.10内核时候,使用PCIE转USB上使用USB3.0,即XHCI协议时总是会报这样的警告: xhci_hcd 0000:14:00.0: WARN Successful completion on short TX: needs XHCI_TRUST_TX_LENGTH quirk? xhci_hcd 0000:14:00.0: WARN Successful completion on short TX: needs XHCI_TRUST_TX_LENGTH quirk?
I enabled xHCI module in kernel and I am able to see our USB 3.0 camera. We are also using a Renesas UPD720202 chipset as a PCIe-2-USB3.0 bridge. The device is well detected on our system and enumerates as a gen2 device. Dump for PCIE: [ 0.472685] OF: PCI: host bridge /soc/...

Hello all, I'm having some trouble getting a PCIe usb controller working with my system and I'm not sure where the exact problem is. As an FYI, I am...
作为参考、我们有另一个具有 TUSB7320主机的电路板(是的、仅具有2个端口的器件稍有不同)基于 Xilinx Zynq-7000芯片、在 FPGA 结构中启用了 PCIe 根子系统、并在同一 Linux 内核(为 armv7/Xilinx_Zynq_defconfig 构建)上运行、使用了相同的 xhci-hcd 驱动程序。...
PCIe是标准接口，xHCI控制器只要提供PCIe接口也就是PCI配置空间访问、寄存器访问、内存访问之类就可以了，...
