Hi Markus,
I assume you are using the driver from the 'dde_linux' directory, right? There is another USB driver in the 'linux_drivers' repository on github which can also handle HID devices. To tell you the truth, the 'dde_linux' version has not been tested on x86-hardware so far, since we mostly concentrated on PandaBoard support lately. So I have to admit that you're a sort of an alpha tester here. Anyway, I can test the thing on some box tomorrow, since it actually does not look that bad. The UHCI controller (where HID devices usually reside) has been detected. My first uneducated guess here would be that the driver does not get any interrupt from the controller. Could you enable 'DEBUG_IRQ' in 'dde_linux/src/drivers/usb/lx_emul.h' and check if the 'dde_linux/src/drivers/usb/signal/irq.cc:handle()' function gets actually called? If not please start the 'acpi_drv' beforehand, since it might find a different (to the one in the PCI config space) interrupt number for the controller within the ACPI-tables. That's usually the fun on kernels that use APICs.
Thx for reporting and please keep me informed about your insights,
Sebastian
P.S. If nothing works please also send your Genode configuration file.
DEBUG_IRQ revealed no real news for me, except for the fact that IRQ 10 was discovered, but apparently no interrupt came in, handle() was not called once.
So I added acpi_drv to my setup, resulting in a different log. As you suggested, I attached the new log as well as my configuration file.
Another interesting fact is that, when the iommu flag of the hypervisor is removed, it looks quite different already. A log file of this behavior is also attached.
Regards
Markus
