Hi all, I am trying to port usb_ohci code (u-boot-1.1.3 version) from cpu/arm920t/s3c24x0 to our chip. I added low_level specific functions and It seems to work correctly with a low speed device (mouse...). Things get a little more compilcated when I use a disk-on-key. when I perform a : usb start

U-Boot> usb start (Re)start USB... USB: scanning bus for devices... 2 USB Device(s) found scanning bus for storage devices... ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT ERROR: CTL:TIMEOUT Device NOT ready Request Sense returned 00 00 00 0 Storage Device(s) found

But when I perform a usb tree I get this : U-Boot> usb tree

Device Tree: 1 Hub (12MBit/s, 0mA) | OHCI Root Hub | +-2 Mass Storage (12MBit/s, 94mA) M-Sys DiskOnKey 2730C3409173AB63

or a usb info :

U-Boot> usb info 1: Hub, USB Revision 1.10 - OHCI Root Hub - Class: Hub - PacketSize: 8 Configurations: 1 - Vendor: 0x0000 Product 0x0000 Version 0.0 Configuration: 1 - Interfaces: 1 Self Powered 0mA Interface: 0 - Alternate Settings 0, Endpoints: 1 - Class Hub - Endpoint 1 In Interrupt MaxPacket 2 Interval 255ms

2: Mass Storage, USB Revision 2.0 - M-Sys DiskOnKey 2730C3409173AB63 - Class: (from Interface) Mass Storage - PacketSize: 64 Configurations: 1 - Vendor: 0x08ec Product 0x0012 Version 2.0 Configuration: 1 - Interfaces: 1 Bus Powered 94mA Interface: 0 - Alternate Settings 0, Endpoints: 2 - Class Mass Storage, Transp. SCSI, Bulk only - Endpoint 1 In Bulk MaxPacket 64 - Endpoint 2 Out Bulk MaxPacket 64

But when I perform a usb storage I get this :

U-Boot> usb storage No storage devices, perhaps not 'usb start'ed..?

Do you know why all this mess around the disk-on-key ?

Do you know how to solve this ?

Should I try code from cvs instead of that of 1.1.3 version ?

Best regards,

Amine.
