When I unplug or plug my usb device, I can see port change interrupt received my handler. But I say the host command is 0x00010009, that means Asy is not enabled. If Asy is not enabled, host cannot send control qtd to device. Did linux driver enable it when send control pipe then disable it after finishing it? If so, where it is? appreciate your help, vichy > ----- Original Message ----- > From: "vichy" <vichy.kuo@xxxxxxxxx> > To: <linux-usb@xxxxxxxxxxxxxxx> > Sent: Monday, March 16, 2009 7:56 PM > Subject: Re: Drivers need for usb file system > > > 2009/3/12 Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>: >> >> On Thu, 12 Mar 2009, Greg KH wrote: >> >>> On Thu, Mar 12, 2009 at 10:26:47PM +0800, vichy wrote: >>> > Dear all: >>> > I am porting ehci-host driver on my arm platform. >>> > So far the host seems correctly enabled, but I have no idea how to >>> > read the contents of USB storages as Ubuntu does. >> >>> > And I decide to build the drivers I need one by one. >>> > If someone knows the whole list of drivers I need, please let me know. >>> > ( The module utility is fail on my platform, so I use build-in to >>> > develop driver.) >>> >>> usb-storage. >> >> You also will need scsi_mod (which is required by usb-storage) and >> sd_mod. >> >> Alan Stern > > Hi: > I use uclinux to port ehci host and I have 2 questions below: > 1. > When porting the host driver, I have error message as below. > EHCI_TEST-ehci EHCI_TEST-ehci.0: port 1 high speed > EHCI_TEST-ehci EHCI_TEST-ehci.0: GetStatus port 1 status 00000d > sig=se0 PEC PE CONNECT > usb 1-1: device descriptor read/64, error -110 > EHCI_TEST-ehci EHCI_TEST-ehci.0: port 1 high speed > EHCI_TEST-ehci EHCI_TEST-ehci.0: GetStatus port 1 status 00000d > sig=se0 PEC PE CONNECT > usb 1-1: device descriptor read/64, error -110 > EHCI_TEST-ehci EHCI_TEST-ehci.0: port 1 high speed > EHCI_TEST-ehci EHCI_TEST-ehci.0: GetStatus port 1 status 00000d > sig=se0 PEC PE CONNECT > usb 1-1: new high speed USB device using EHCI_TEST-ehci and address 3 > EHCI_TEST-ehci EHCI_TEST-ehci.0: port 1 high speed > EHCI_TEST-ehci EHCI_TEST-ehci.0: GetStatus port 1 status 00000d > sig=se0 PEC PE CONNECT > usb 1-1: device descriptor read/64, error -110 > EHCI_TEST-ehci EHCI_TEST-ehci.0: port 1 high speed > EHCI_TEST-ehci EHCI_TEST-ehci.0: GetStatus port 1 status 00000d > sig=se0 PEC PE CONNECT > usb 1-1: device descriptor read/64, error -110 > EHCI_TEST-ehci EHCI_TEST-ehci.0: port 1 high speed > EHCI_TEST-ehci EHCI_TEST-ehci.0: GetStatus port 1 status 00000d > sig=se0 PEC PE CONNECT > usb 1-1: new high speed USB device using EHCI_TEST-ehci and address 4 > usb 1-1: device not accepting address 4, error -110 > EHCI_TEST-ehci EHCI_TEST-ehci.0: port 1 high speed > EHCI_TEST-ehci EHCI_TEST-ehci.0: GetStatus port 1 status 00000d > sig=se0 PEC PE CONNECT > usb 1-1: new high speed USB device using EHCI_TEST-ehci and address 5 > usb 1-1: device not accepting address 5, error -110 > > The error comes from hub_port_connect_change, while doing the config_tries. > Is there debug option which can let me see the content of urb such > that I can make sure the qhd is properly set. > > 2. from the message at the end of letter, it seems I duplicate my > driver in sysfs. > I have searched the source but I cannot find out where it is. > what I do is modifying ehci-au1xxx.c. > Does the problem 1 come from problem2?
