Hi,

I am doing the USB MAss storage testing on BF527 ezkit. I have followed the configurartion settings as in

docs.blackfin.uclinux.org/doku.php?id=hw:cards:usb_ez-extender#test_usb_mass_stroage

The connection is as follows,

USB Mini B socket connected to the USB OTG Port on the BF527 Board and USB A Female socket connected to the USB Flash disk.

1.After booting the kernel, when I plug the USB Flash disk to the USB Port, I am not getting any message on my Serial Port Terminal.

Can you please help me out to fix this problem?

Could you post your kernel boot message here?

How about build kernel for 0.2 revision and try again?

Hi Mike,

The kernel settings are as follows,

[Linux Kernel Configuration] -→ [Device Drivers] -→ [USB support]

<*> Support for Host-side USB

[*] USB device filesystem

[*] USB device class-devices (DEPRECATED)

<*> Inventra Highspeed Dual Role Controller (TI, ADI, ...)

--- Blackfin BF54x high speed USB support

Driver Mode (USB Peripheral (gadget stack)) --->

[ ] Disable DMA (always use PIO)

(0) Logging Level (0 - none / 3 - annoying / ... )

These settings are done as per the document given in

https://docs.blackfin.uclinux.org/doku.php?id=usb_peripherals

Please tell me, Is there any other setting that should be done in order to disable the hub?

the hub has nothing to do with your configuration settings. the hub exists in whatever you're plugging into the USB port. dont plug in a hub.

some flash disks have hubs built into them. find a different device to test with.

the "usb hub" message doesnt lie. if it that is displayed, a hub is in the chain, and it isnt going to work.

Mike, I'm a bit confused on this as well. I'm using an ISP1362 which has two USB ports. To the USB subsystem, the chip appears as a hub. Both ports work fine (except for some apparent driver issues which I'm mentioned in a different thread.) On boot, mine always looks like this (with no USB devices plugged in):

AFAIK, all devices with multiple USB interfaces appear as a hub. Are you saying these chips are not supported by the current build?

you arent using the Blackfin on-chip USB interface. thus nothing in this thread applies to you.

Hi.

I do not know if you prefer me to start another thread, but I am facing same behaviour as in here.

I am trying to use the OTG interface of a bf527 as a host, and connect a pen-drive to it.

Although I can see that there is some kind of interaction in the line using an oscilloscope, the kernel does not detect the pen-drive (I have also tried with other devices).

This are the significative traces relating USB in the kernel boot:

"usbcore: registered new interface driver usbfs

usbcore: registered new interface driver hub

usbcore: registered new device driver usb

musb_hdrc: version 6.0, pio, host, debug=0

musb_hdrc: USB Host mode controller at ffc03800 using PIO, IRQ 59

musb_hdrc musb_hdrc.0: MUSB HDRC host driver

musb_hdrc musb_hdrc.0: new USB bus registered, assigned bus number 1

usb usb1: configuration #1 chosen from 1 choice

hub 1-0:1.0: USB hub found

hub 1-0:1.0: 1 port detected"

and this is part of the kernel configuration in one of my trials:

"CONFIG_USB_MUSB_HDRC_HCD=y

CONFIG_USB_OTG_BLACKLIST_HUB=y

CONFIG_IRQ_USB_EINT=10

CONFIG_IRQ_USB_INT0=11

CONFIG_IRQ_USB_INT1=11

CONFIG_IRQ_USB_INT2=11

CONFIG_IRQ_USB_DMA=11

CONFIG_USB_MUSB_HDRC_HCD_CLK=20

CONFIG_USB_MUSB_HDRC=y

CONFIG_USB_MUSB_HOST=y

CONFIG_USB_MUSB_SOC=y

CONFIG_USB_MUSB_DEBUG=y

CONFIG_BLK_DEV_UB=y"

Is there any additional information that I can offer?

Thanks in advance for your help and advice.

Miguel Ángel

Dear Mike

I read the documentation before beginnign to configure the kernel, but I am sure I am missing something.

As far as I know i am not using an external hub, and I have even configure "CONFIG_USB_OTG_BLACKLIST_HUB=y" in the kernel in order not to take into account external hubs.

I am connecting my devices directly to the USB interface (which basically is the USB lines in the BF527), so... I cannot understand why it is detecting an external hub.

Any clues?

What device are you plugging in, and does it have a built in hub (many devices do). Have a look on your host with "lsusb -t".
