Does have UR22 first version glitches?

Hey, I’m about to buy Steinberg UR22 1st generation from my friend. My other friend told me that 1st generation have glitches and bugs, is that right? I’ve searched the forum and found . Luckily, that serial number isn’t listed there so it should be okay. Also found that it has problems with asRock motherboard, luckily I have MSI motherboard, should everything be okay? Is that only 2 problems? And what about preamp quality etc.? Is it the same as MKII?
