Can I use this to connect a firewire mixer to my laptop through usb 2.0 or 3.0?

No you can not connect firewire to any sort USB ports. Fire wire and Usb are two different dinosaurs. Fire wire sends a signal kinda like this ------------------------------------------- ------------------------------------------- where usb sends signals like this --- --- --- --- While there are some supposed USB to PCMCIA or even Express Card adapters on the market. You can not use a Firewire card in such adaptor, because the same signal issues. You have a USB BUS and also a PCI bus that interface with an Express Card slot or PCMCIA slot. Firewire HAS to interface with the PCI aspect of it. Due to the way the firewire sends its signal. It just will not work. Trust me on this one. For Laptops with such Express Card slots try an older Dell E latitude series. There is also a handful of laptops out there if you search hard enough for such slots, and or still have A T.I. Firewire chipset built in. They are getting harder to find, and they are much more $$$ than the average consumer laptop sadly. The fact is people who use firewire devices are far and few between. So Hopefully manufactures of Audio devices will adapt to the USB 3.0 or the future the USB 4.0 (not out yet) instead of firewire. for an attempt at lossy formats.

Can this be connected into an ExpressCard adapter (since I don't have an ExpressCard slot in my computer)?

What chipset is used in the StarTech EC13942?

It is NOT a TI chipset. It is a VIA -- I just installed one as of June 2016 and am very disappointed that it wasn't TI.

is it work for laptop hp-G72?

According to the specifications listed for your laptop, the answer is no. This will only work with laptops equipped with 34mm or 54mm ExpressCard slots (commonly known as PCMCIA slots). Many laptop makers are phasing out these types of slots.
