we have also noticed the issue you're describing, but only with some motherboards and the only known workaround at the moment is what you already found - "disable remote control polling in the dvb_usb module", which effectively disables the remote control. however, it's not clear what causes the issue, because on the same Linux installation and kernel version if we replaced the motherboard with another one the problem is gone. so, maybe it's fault of USB port/chipset and Linux kernel driver for it and not V4L. for example we reproduced the problem with old and new kernels on AMD 785GT based motherboard, but on another motherboard with old VIA chipset it's not there. what is the chipset of your motherboard? it's interesting to collect more information about this issue.
@Jérome
please, tell us you motherboard chipset too.
thanks,
