I'd rather wish I'm going to made stupid guy myself again but I fear this wont happen :(
1. USB
------
I guess there are not many ppl who already fully tried and tested that USB thing, right? I even don't know how Nature guys tested it...
What's the problem? Well, the basic ground of the USB connector -- no +5V at all! I tested both of my ethernats, addr/data buses on ct63 and everything is ok except that USB connector on ethernat board -- absolutely silent :((( I suppose there's no magic switch to power on USB, right? I tested it with multimeter on both USB connectors... DAMN IT!
Please, could someone take some measure device and test for +5V at ethernat board? Pinout is here: http://groups.google.at/group/comp.sys.atari.st/browse_thread/thread/c5a43c4608eeadb0
2. IDE/SCSI transfer errors
---------------------------
I know there is a little design flaw in ct60/ct63 which prevents us to use full 100 MHz along with ethernat (or any other device). But to my surprise, 85 MHz isn't safe anymore, too!
I noticed some very, very strange behaviour since I installed ethernats (I thought it's because of faulty cable and/or hdd, so I replaced them with new ones) and I couldn't solve it. After many and many hours of endless md5sum tests (it appeared to show the error in the files of tens of MB in size) I found in 030 mode everything is working ok -- write to disk, read from disk.
In 060 mode, however, even the files which were written correctly in 030 mode appeared to have bad md5sums! There were altered just really small amount of bytes in such files -- maybe one byte per 100 MB... After another batch of experiments I've got it -- lowering 060 to 66 MHz solved the thing!
And now the finale... I removed ethernat... switched back to 85 MHz... and voila! md5sums are correct! (and yes, I've tried to switch back to 85 MHz with ethernat installed -- md5sums failed again)
I don't know why exactly this happens to me but it really efficiently kills my motivation to code anything :( Two weeks passed and I didn't write one single fucking line of code :(

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
