Hi, has anybody tested the TotalLUNs functionality for the usb-stack? When I`m defining it to 3 there is only the scsi inquiry, request sense, ... for lun 0. Lun 1 and 2 is ignored.

Does anybody knows whats going wrong?

Regards

Daniel

Hi all,

I solved the problem. Windows prohibits Multiple LUNs if theres no serialnumber in the usb descriptor

So I changed the .SerialNumStrIndex in the Descriptors.c to 0x04 and added

uint8_t SerialNoString[] =
{
USB_STRING_LEN(12),
DTYPE_String,
WBVAL('U'),
WBVAL('C'),
WBVAL('R'),
WBVAL(' '),
WBVAL('0'),
WBVAL('0'),
WBVAL('0'),
WBVAL('0'),
WBVAL('0'),
WBVAL('0'),
WBVAL('0'),
WBVAL('1'),
};
USB_Descriptor_String_t *SerialNoStringPtr = (USB_Descriptor_String_t*)SerialNoString;

and added in function CALLBACK_USB_GetDescriptor in case DTYPE_String the case 0x04

Address = SerialNoStringPtr;
Size = pgm_read_byte(&SerialNoStringPtr->Header.Size);
break;

Regards

Daniel
