-> Hi,
-> 
-> I've got two different MultiTech USB devices. One is a PSTN MTA5634ZBA-USB 
-> modem and the other is an ISDN MTA128ST-USB.
-> 
-> Now, running on NetBSD 1.6, the PSTN device is detected fine, no problems, b
-> ut 
-> the ISDN device gets the kernel to return the following message :
-> 
-> uhub0: device problem, disabling port 1
-> 
-> After sticking in a few printouts in the kernel I found (from what I can 
-> see) when a new usb device is detected, the kernel expects a certain
-> amount of transfers from the device, each of a certain size.
-> 
-> Now the PSTN device (the one that works) first transmits 8 bytes followed 
-> by 18 bytes followed by a whole lot of other transfers of varying sizes. 
-> I assume these all contain product, vendor info etc.. Now the ISDN device 
-> transmits the 8 bytes for the first transfer but only seems to transmit 8 
-> bytes for the second when the kernel is expecting 18 bytes.
-> 
-> Now what I'd like to know is if this is a quirk, and how exactly I can set 
-> this up to properly detect the device.

I've CC'ed Lennart, the NetBSD USB guru because this isn't the first time
this sort of bug has been reported, and I've got a USB devices that also
seem to suffer a similar fate.  Hopefully, Lennart will have a "oh, that's
easy, just add this" answer :-)
