[speedtouch] USB read timeout with PIIX3 USB

[Vladimir Vyskocil]

Hi,

I'm investigating the lock out I have on my board with a USB Controller: Intel Corp. 
82371SB PIIX3 USB [Natoma/Triton II] (rev 1). 
I have found that pppoa2 (I don't tried with pppoa3 for now) from 
speedtouch-CVS_03_03_2002 package block from time to time a this line in pppoa2.c :

n = pusb_endpoint_read(epdata, lbuf, sizeof(lbuf),  0);

When the lock append, I must wait that my cron script 'checkadsl' ping remote ppp 
adresse and then restart pppd. pppoa2 get stucked at this line waiting for data that 
never come (i don't know why ?) until the script kill pppd.

I changed this line to 

n = pusb_endpoint_read(epdata, lbuf, sizeof(lbuf),  30000);

And now I don't have lockout anymore ! But when there is no data transfert for 30s I 
get these lines in /var/log/syslog : 

May  1 22:48:54 hector kernel: usb_control/bulk_msg: timeout
May  1 22:48:54 hector kernel: usbdevfs: USBDEVFS_BULK failed dev 3 ep 0x87 len 3392 
ret -110

It seems that something better should be done in the driver, as I saw that I'm not 
alone with this problem.

Vlad.
