There is currently an issue in the AMD Adrenalin drivers (17.12.1+) that makes pciebus detection impossible. AMD is aware of the bug and hopefully there is a new version that fixes it soon. Update: 18.1.1 Alpha drivers tested and bug remains.

In a functioning driver, a query returns the PCIe bus ID for each GPU, however in the Adrenalin drivers a bus ID of 0 is always returned.
This bus ID is necessary to query the AMD Display Library (ADL). Because bus IDs are not actually being returned, ADL cant get information like temperature/usage, UUID, PCIe location, etc.

So i found what is causing the problem, but i don't understand how does Claymore miner detect busid on those drivers. ?

I can add a parameter where you can manually enter busid, and it should work. It's easy to get PCI bus id from device manager.

well that an old bug.. and pretty well known... not only claymore miners, but sgminer-gm correctly work with AMD`s moreover gateless gate miner sharp (written in managed c# and using cloo lib) is doing the same.
so it`s look quite possible. you can check on how open source(sgminer gm or gateless gate sharp) stuff is doing that )
if you need help as a bet tester, i am willing to do so.
I do believe you can do it )
