Hi, ehci_disown() means that there should be a full speed controller that should handle the device, because it is not high-speed
Ok
Does your board have OHCI/UHCI or only EHCI?
It's EHCI/OHCI... from the A20 User Manual revision 1.3 @ http://dl.linux-sunxi.org/A20/
--- start ---User USB Host controller is fully compliant with the USB 2.0 specification, Enhanced Host Controller Interface (EHCI) Specification, Revision 1.0, and the Open Host Controller Interface (OHCI) Specification Release 1.0a. The controller supports high-speed, 480-Mbps transfers (40 times faster than USB 1.1 full-speed mode) using an EHCI Host controller, as well as full and low speed through one or more integrated OHCI host controllers.
--- end ---
Acording to https://github.com/OLIMEX/OLINUXINO/blob/master/HARDWARE/A20-OLinuXino-LIME/A20-OLinuXino-Lime_Rev_C.pdf, the two USB Host connectors are wired through a SY6280 for 5V power control and current limiting, but otherwise, D+ and D- are directly wired to the A20 which has an integrated PHY. A20-OLinuXino-Lime_Rev_C.schHow are the USB parts wired.
Is there a High-Speed TT (USB HUB chip) connected to the EHCI port?
No
Can you compare dmesg from Linux and FreeBSD and look for the USB parts.
Both dmesg outputs below have been selectively edited to remove non-USB related output for brevity.
