Re: [U-Boot] usb reset issue with some pen drives which work well in Linux/Windows
Dear Mr. Wolfgang, I found the issue. In usb_stor_get_info function of common/usb_storage.c I add the following: (dev-descriptor.idVendor == 0x0204 dev-descriptor.idProduct == 0x6025) to skip the ss-transport_reset(ss);. This I took out from the linux kernel code. Now its working for me.

[U-Boot] usb reset issue with some pen drives which work well in Linux/Windows
Hello, I was trying to add usb support to u-boot for my Arm cortex-A9 processor based board. I am using U-Boot 2009.08. I have tested the usb support (reset, fatls, fatload to boot linux etc) with the following devices and its working fine. 1. Western Digital My Book - Self powered USB HD 2. Western Digital My Passport - Bus powered USB HD 3. Transcend 4GB Pen drive - 2 makes However one issue still remains. It is not working with some usb pen drives (which works with Linux and windows). I have done the testing on 1. Dane-Elec 2 GB Pen drive 2. nxp 256 MB pen drive It seems these are some non-standard usb devices. With these devices uboot-usb is able to detect it, however during the mass storage scan, reset is getting failed (getting stall) and the following message we are getting: scanning bus for storage devices... 0 Storage Device(s) found Check the file - common/usb_storage.c. Function- usb_stor_BBB_reset : USB_STOR_PRINTF(RESET:stall\n); I googled it however have not come across any fix so far. Then I took the latest u-boot i.e. u-boot-2010.09 and back ported the usb stack. With that the usb reset is a success and it is able to detect it as a mass storage device. Commands like usb storage, usb tree etc showing proper information about the pen driver. However File System commands like fatls is not working. For USB support I have added the folling config stuffs to my file in include/configs #define CONFIG_CMD_USB #define CONFIG_USB_STORAGE #define CONFIG_USB_EHCI #define CONFIG_USB_EHCI_PNX84XX -- My usb config #define CONFIG_EHCI_HCD_INIT_AFTER_RESET #define CONFIG_SUPPORT_VFAT Is this a know issue or I am doing something wrong. Please help me in resolving this issue. Regards Debashish Rath Trident Microsystems ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
