(یہ جواب مذکورہ تناطر میں ہے)

Microsoft has developed a massive pool of IT terms in collaboration with National Language Promotion Department, Islamabad.

I would strongly recommend using those terms for IT as hundreds of linguists are already using this source and it is becoming a coherent source throughout the world for Urdu translators.

Now your given sentence:
Tap OK on the USB debugging pop-up that appears on your Gear 2
اپنے گئیر 2 پر نظر آنے والے یو ایس بی درستی پاپ اپ پر اوکے کو تھپتھپائیں۔

Actually, none of our suggested translations alone would convey the full message behind this technical term because debugging is the process of locating and fixing or bypassing the bugs or errors in a computer program code or the engineering of a hardware device. So,we can define it in Urdu language (sentence or phrase) but can't use a single term. So, I'll suggest to use a suitable Urdu word while keeping the transliteration in brackets, at least for the first time in the document.
