Strange Phenomenon During USB Connection

[yohannie]

When Infuse is connected to my laptop (Sony VAIO) via USB, for some reason, the screen's response becomes slurred and at times nonfunctional. As soon as I unplug the phone from my laptop's USB, the screen comes right back to being responsive and snappy. This happens regardless of whether I choose "Mass Storage" or just not connect (usually when I just want to charge).

Interestingly, when my phone is connected to a wall electric outlet, it has no issues. The screen doesn't get affected at all. Also, I noticed that at work, when I connect my phone to a Dell PC desktop via the USB method, the screen stays responsive and happy.

This is my second Infuse, and I noticed the same thing on both phones.

It's not causing me any devastating losses, but I'm just curious why this is happening. I noticed that some Captivate users also experienced a similar phenomenon. It's strange that only when the phone is connected to certain USB/computers that the screen (of all things) becomes unresponsive or weird.

I know there is some secret bad blood between Samsung and Sony (my Sony VAIO will refuse to work with my Samsung TV, while all other brand laptops work fine), so I'm wondering if this is another case like that.

Is it possible that it is automatically starting a virus scan, or doing some other sort of device check? It sounds like it is "busy" doing something. I haven't had this happen with my phone, that I'm aware of, but I know if I connect some devices to my laptop it will scan that new device.

Oh wow that's a very interesting thought! Come to think of it, my laptop is automatically set to run Symantec checks on anything that gets connected. But it happens even when I don't choose the "Mass Storage" option on the phone after connecting... Do you think the laptop is still able to access the phone even though it's just plugged in?

I don't know. If you don't select mass storage on the phone I don't know what the laptop sees.

I would think that if it was a virus scan it would end shortly and the phone would respond normally. I would try disabling the scanner before connecting the phone and see what happens. If that doesn't work it may be something else on your laptop since connecting at work doesn't have the same effect.
