xHCI over PCI
|
||||
-------------
|
||||
|
||||
xHCI support was tested on x86_64 target, both on QEMU and real hardware.
|
||||
|
||||
Known issues with this driver:
|
||||
|
||||
- Currently only USB2.0 is supported, there is no USB3.0 support in NuttX yet.
|
||||
|
||||
- USB HUB devices not supported yet
|
||||
|
||||
To enable xHCI support on QEMU, we have to add ``-device qemu-xhci`` argument.
|
||||
All supported USB devices in QEMU can be found in
|
||||
`QEMU documentation <https://qemu-project.gitlab.io/qemu/system/devices/usb.html>`_,
|
||||
but not all classes are supported in NuttX.
