I found an lsusb output from trying it on my laptop a while back at http://ccrma-mail.stanford.edu/pipermail/planetccrma/2002-December/000796.html . It looks like the same error: Bus 001 Device 010: ID 0582:0006 Roland Corp. Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.00 bDeviceClass 0 Interface bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 8 idVendor 0x0582 Roland Corp. idProduct 0x0006 bcdDevice 1.10 iManufacturer 1 Roland iProduct 2 UA-30 (44100Hz, Analog REC) iSerial 0 bNumConfigurations 1 cannot get config descriptor 0, Connection timed out (110) Language IDs: (length=4) 0409 English(US) I'm now getting: Bus 001 Device 003: ID 0582:0006 Roland Corp.

Could it be a problem with the UA-30 refusing to return config descriptor 0, whatever that is, when the program asks for it? The closest thing I've seen to documentation of the config descriptors is at http://www.beyondlogic.org/usbnutshell/usb5.htm##ConfigurationDescriptors (yes, two # signs are needed), but I'm not following what this means. http://groups.google.com/groups?q=lsusb+%22cannot+get+config+descriptor%22&hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=20021106132022.GA2101%40home.ldb.ods.org&rnum=1 seems to suggest that this may be a kernel bug, though it's not about the kernel that I'm using, and I was using different ones on the two systems. It looks like I'm using an up-to-date lsusb now: [root@localhost Documents]# lsusb --version lsusb (usbutils) 0.11 [root@localhost Documents]# urpmi usbutils Everything already installed [root@localhost Documents]# And the error seems to show up more than once: [root@localhost Documents]# lsusb -v | grep cannot Invalid product/subclass spec at line 2650 Language IDs: none (cannot get min. string descriptor; got len=-1, error=32:Broken pipe) Language IDs: none (cannot get min. string descriptor; got len=-1, error=32:Broken pipe) cannot get config descriptor 0, Connection timed out (110) Language IDs: none (cannot get min. string descriptor; got len=-1, error=110:Connection timed out) cannot get config descriptor 0, Connection timed out (110) Language IDs: none (cannot get min. string descriptor; got len=-1, error=110:Connection timed out) [root@localhost Documents]# I'm attaching the complete lsusb -v output. >> Well, there are other ways to get the descriptors.
