Thanks for that tip but it made no difference to me. I need to look deeper into that problem. Just a bit of a context here. I'm playing with ARC SP board which consists of 2 parts: [1] Baseboard with all peripherals and their connectors [2] Daughterboard with CPU and DDR Baseboard is connected to CPU-board via AXI tunnel. And when CPU-board is the one with ASIC based on ARC770 that runs at 700 MHz I see USB 2.0 working perfectly fine. But if I use CPU-board that sports FPGA with ARC HS38 CPU running at 75 MHz I see the first asynchronous tarnsaction on US 2.0 never happens. In particular in ehci_submit_async() after we enable async. schedule setting CMD_ASE command STS_ASS gets set but then token's status stays active forever i.e. following is always true: --------------------->8--------------------- QT_TOKEN_GET_STATUS(token) & QT_TOKEN_STATUS_ACTIVE --------------------->8--------------------- Note USB host controller, phy and usb dongle are exactly the same. And USB 1.1 (OHCI) works perfectly fine at the same time. Any ideas what could be wrong? -Alexey

I remember seeing that stuff multiple times before, but it might be a different issue. It was usually triggered by some sort of corruption during the transfer.

Uh, sorry I didn't get back to you about this. I am wrestling my own issues with the DWC2 USB core :-/ Looks like it doesn't work with USB3340 LPM-capable PHY (it only starts in FS mode), but works with non-LPM-capable USB3300 PHY and starts in HS mode. Did you figure your issue out by any chance ?

No unfortunately I wasn't able to figure out what's wrong there. For now I parked this activity waiting for response from our hardware guys. I spent way too much time on that and basically need to switch to other high-priority things. If I ever get that problem resolved I'll let you know. And thanks for your time anyway, that's much appreciated! -Alexey

Please let me know what was it, I'd be interested in what went wrong for future reference. > If I ever get that problem resolved I'll let you know. > > And thanks for your time anyway, that's much appreciated! Thanks! btw can you put me in touch with some guys who work on the DWC2 OTG core? I have a few questions of my own, in particular with regard to the USB3340 PHY, which seems to have issues with the DWC2. Best regards, Marek Vasut

This commit adds support of USB 1.1 storage media on AXS103 board. For some yet unknown reason USB 2.0 doesn't work on AXS103 board issuing messages like this: ------------------------>8------------------- AXS# usb start starting USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... EHCI timed out on TD - token=0x80008c80 unable to get device descriptor (error=-1) 1 USB Device(s) found ------------------------>8------------------- As a work-around we're falling back to USB 1.1. Indeed it is much slower but at least USB storage devices are usable on AXS103.
