Description

I need /proc/bus/usb/devices, because the module list shows pl2303 and it is a radically different driver from the Multitech's driver cdc-acm. Actually, since this is RHEL *3*, please test this kernel in your setup: ftp://people.redhat.com/zaitcev/rhel3usb/ Err, ignore the reference to the acm, I confused this issue with bug 165453. However, please do give me the /proc/bus/usb/devices, and please test the experimental kernel. $ cat proc/bus/usb/devices T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 4 B: Alloc= 18/900 us ( 2%), #Int= 1, #Iso= 0 D: Ver= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0000 ProdID=0000 Rev= 0.00 S: Product=USB OHCI Root Hub S: SerialNumber=f888d000 C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub E: Ad=81(I) Atr=03(Int.)

Try 2.4.21-31.EL.usbserial.5 in ftp://people.redhat.com/zaitcev/rhel3usb/ I want to be sure that it doesn't deadlock. If it does, please get me sysrq-t. Reopening, this occurs with the 2.4.21-31.EL.usbserial.5smp kernel.
