Re: [usbip-devel] USB/IP

[Valentina M. <val...@gm...>]

Hi Constantine,

The most up-to-date version of the Linux version of USB/IP can be
found here [1], in Greg Kroah-Hartman's Linux tree (just use git clone
<URL> to clone it).

Yes. You should use the kernel version in the above mentioned tree as
USB/IP is guaranteed to work with it.

The distro doesn't really matter. I, personally, had issues with Linux
Mint when using another kernel in the sense that the GUI wouldn't load
any more, but if you're using VMs only for testing USB/IP and
developing someplace else, you don't even need GUI. I'd say you should
go with whatever distro you like.

Just like in other C software projects, gdb and printk/printf are your
best friends.

However, I should point out that this driver is already under active
developement (I am working on it as part of OPW); this means you
should always make sure you have the latest source version.

Hope I was able to help.

Thanks,
Valentina
