I use to use my infinix x600 USB charger cord to transfer file s to my laptop. But yesterday I tried it and I could not see any logo on my computer, even though it clearly showed on my phone screen that I connected the phone. After much struggle from USB debugging, to trying to update the device, it only now shows me a CD ROM drive (e) and it say insert disc. Engineers why is my laptop not recognising my phone anymore. How can I make it work. I suspect driver issue, but after much struggle they said I should contact the manufacturer and gobto their website to get solution to download. I tirer.
