Hello,
I am trying to get a Linksys USB-to-Wireless adapter working with the OSK. I started
off by trying to check if the USB Master interface works using a Flash disk. When I
plug in the USB disk, I see that usb interrupts do not occur.
I'm using a linux-2.4.16 kernel, patched with omap1 patch from www.muru.com. I've
configured and built the kernel for OSK with the USB support according to the document
at OSK for dummies:
Device Drivers --->
USB support --->
<*> Support for host-side USB ( CONFIG_USB )
<*> OHCI HCD support( CONFIG_USB_OHCI_HCD )
<*> USB Mass Storage Support( CONFIG_USB_STORAGE )
SCSI device support --->( CONFIG_SCSI )
<*> SCSI disk support( CONFIG_BLK_DEV_SD )
"File systems" --->
"DOS/FAT/NT Filesystems" --->( CONFIG_FAT_FS)
<*> MSDOS fs support( CONFIG_MSDOS_FS )
<*> VFAT ( Windows-95 fs support)( CONFIG_VFAT_FS )
"File systems" --->
"Partition Types" --->
[*] Advanced partition selection( CONFIG_PARTITION_ADVANCED )
[*] PC BIOS (MSDOS partition table)( CONFIG_MSDOS_PARTITION )
"File systems" --->
"Native Language Support" --->( CONFIG_NLS )
<*> Code Page 437 (United States...)( CONFIG_NLS_CODEPAGE_437 )
<*> NLS ISO8859 (Latan 1...)( CONFIG_NLS_ISO8859_1 )
As far as my understanding goes, irrespective of whether the
device has been configured for USB Mass storage or not, if the
device is recognized, USB interrupts should occur, which is not
happening.
cat /proc/interrupt returns:
CPU0
19: 0 DMA
20: 0 DMA
21: 0 DMA
22: 0 DMA
23: 0 DMA
24: 0 DMA
25: 0 LCD DMA
31: 3 omap-lcdc
33: 1 omap-keypad
36: 0 i2c_omap
38: 0 ohci_hcd:usb1
46: 548 serial
54: 158278 32KHz timer
85: 0 DMA
86: 0 DMA
87: 0 DMA
88: 0 DMA
89: 0 DMA
90: 0 DMA
91: 0 DMA
92: 0 DMA
93: 0 DMA
94: 0 DMA
160: 1399 eth0
197: 0 serial wakeup
222: 0 omap_cf
Has anyone successfully got the USB Master interface on the OSK5912
to work fine?
Thanks in advance,
Regards,
Kanagesh

Hello,
My apologies, the kernel that I am using right now is linux-2.6.13-omap1 (and not
linux-2.4.16 as mentioned).
Further, I found from the list archives that there was a USB clock malfunction
in kernels 2.6.12 - 2.6.14. I backported my work to 2.6.11-omap1 and I still
see the same problem. However, when the system comes up, I see some stray USB
interrupts (even though there is no device plugged in).
When I plug in a memory disk or any other USB device, there're no USB interrupts.
Can anyone point me to what am doing wrong?
Thanks in advance
regards,
Kanagesh

Hi Kanagesh,
I have the same problem. It is really a clock problem. Try to disable
the CONFIG_OMAP_RESET_CLOCKS options:
System Type ---> TI OMAP Implementations ---> [ ] Reset unused
clocks during boot
I don't know if this error is in the USB subsystem or if it is a bug
in the code
that resets the clocks at boot time.
I would like to know if it worked for you...
