[LAU] Midi controller keeps disconnecting

Hi all,

I recently bought this midi controller:
http://www.musicstore.de/en_EN/GBP/Fame-Tweak-49-Controller-Masterkeyboard/art-SYN0003694-000
It seems to be this Chinese thing:
http://www.worlde.com.cn/products_detail/&productId=1496ebdb-c1c5-401b-b57c-6201634388b3&comp_stats=comp-FrontProducts_list01-1305628296986.html

I was hoping midi is standardized enough that it just works in Linux, it
doesn't ...
But I'd rather keep it, 'cause i don't find anything comparable suiting
my needs for this price.

Now here's the problem:
It basically gets recognized all the way down to alsa

$aconnect -li
client 24: 'USB Device 0x218:0x303' [type=kernel]
   0 'USB Device 0x218:0x303 MIDI 1'

but it keeps disconnecting/reconnecting. The syslog keeps cycling like
this (about twice a second):

Jul 2 03:22:03 pc kernel: [13863.876029] usb 6-1: new full-speed USB

Jul 2 03:22:03 pc kernel: [13864.288055] usb 6-1: USB disconnect,

(I just recognized) That it sometimes even disconnects, before it is
handled by udev

Jul 2 03:26:21 pc kernel: [14122.272020] usb 6-1: new full-speed USB
device number 98 using uhci_hcd
Jul 2 03:26:21 pc kernel: [14122.442212] usb 6-1: USB disconnect,
device number 98

so this is some problem with the drivers/firmware??
Any suggestions are highly appreciated :)

Thanks in advance,
JonnyB

N.B.:
My OS is a Linux pc 3.2.0-45-generic-pae #70-Ubuntu SMP Wed May 29
20:31:05 UTC 2013 i686 i686 i386 GNU/Linux
And yes, it's working in windoze.
Problems with a different device from the same vendor were discussed
here (but seems rather unrelated):
