Is it possible to write with arduino ide

[snopf]

I don't know why it shouldn't be possible but I have no experience with Arduino and I guess it might be more complicated than using the standard gnu tools. Using AVR studio should be possible without any problems as well.
Do you mean compiling or flashing or both?

I want to write hex to tiny85. Is it feasible to use ISP?

[snopf]

Yes that should be possible.
If you want you can write the bootloader (https://github.com/snopf/snopf_bootloader) first (using ISP) and then you can upload the firmware hex using the firmware uploader python tool.

ok
Your hardware has an external crystal oscillator, tiny85 doesn't seem to need a crystal oscillator, right?

You can try without a crystal but you'll have to change the settings in the usb driver.
