Hi Manju,
Does setting USB_MAX_XFER_BLK to 32767 solve this issue?

Hello Fabio,
Hope you are doing well. I needed your help in solving one issue that i am stuck with.
The issue is regarding u-boot 2013.04 version. This version supports USB. The issue i am facing is,
EHCI timed out on TD - token=0x80008d80
This time out error occurs when i flash u-boot first time on the board. But first time even though this error is seen the USB is detected and content of USB can be accessed./
For the second time when i reboot, the same USB key is not detected since i get below error,
U-Boot > usb start
(Re)start USB...
USB0: USB EHCI 1.00
scanning bus 0 for devices... 1 USB Device(s) found
USB1: USB EHCI 1.00
scanning bus 1 for devices... 1 USB Device(s) found
scanning usb for storage devices... 0 Storage Device(s) found
scanning usb for ethernet devices... 0 Ethernet Device(s) found
Please let me know what is your view on this. Since you are a member of u-boot community i am assuming that somebody would have had this issue before. I have tried mailing to u-boot team but i didn't get any response.
I need your help.
Regards, Manju

My understanding is that you use u-boot 2013.04, which is about three years old now ? If you observe some problem, please try with mainline first and report back.

Hello Marek,
I checked with mainline uboot as well. The issue is now clearer. Here are some info:
1. The board uses SMARC module 2. Whenever reboot command is given the usb is detected correctly. 3. When i give a hard reset, the following log is seen.
U-Boot > usb start (Re)start USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... EHCI timed out on TD - token=0x80008c80 1 USB Device(s) found scanning usb for storage devices... 0 Storage Device(s) found
4. Again i boot and do a soft reboot, the same USB is detected.
This is definitely something related to power.
This is something mysterious for me. Anybody has any clue please let me know.
Regards, Manju

Hello Marek,
I checked with mainline uboot as well. The issue is now clearer. Here are some info:
- The board uses SMARC module
- Whenever reboot command is given the usb is detected correctly.
- When i give a hard reset, the following log is seen.
U-Boot > usb start (Re)start USB... USB0: USB EHCI 1.00 scanning bus 0 for devices... EHCI timed out on TD - token=0x80008c80 1 USB Device(s) found scanning usb for storage devices... 0 Storage Device(s) found
- Again i boot and do a soft reboot, the same USB is detected.
This is definitely something related to power.
This is something mysterious for me. Anybody has any clue please let me know.
Try setenv usb_pgood_delay 10000 , increases delay after enabling port power.
Best regards, Marek Vasut
