Will not show up as connected on my mac - SanDisk 2GB Cruzer Micro SDCZ62048A10 Hard Drive

Your MAC can't show you every known video format. Look what format is on the camera and when you put the correct software on the MAC (that came with the camera on CD or DVD) you will be able to import and transfer the video's to the format your MAC can show.

You should update the software on the phone, newer versions will show the MAC address before association. (see https://docs.symbol.com/ReleaseNotes/Release%20Notes%20MC7090%20WM%206.1%20BSP%2001.09.00.htm)

Otherwise, you will need to find an unsecured access point (say, at a local library or Starbucks) and connect to that in order to get to the page that displays the MAC address so you can add it to the secured access point.

You've established that you have a working physical connection. But your network addressing and routing is apparently not setting up.
The usual configuration is to set your Mac to "Using DHCP" and your router or other network interface to provide DHCP addressing. (If the address that shows up in the window on your Mac starts with "169..." it's a bogus address that means your DHCP isn't coming through.)
The most likely culprit here is your router. Take your router out of the chain or command entirely and plug your Mac directly into your network interface (assuming they are not the same box) and see if things suddenly start to work. If so, follow the configuration instructions that came with your router until you get a working connection through it.

Does the camera show up on your desktop when you connect it? If so, just launch iPhoto. Inside iPhoto preferences, check the one that causes iPhoto to launch whenever you attach a camera, and you won't run into this behavior in the future. If the camera does not show up on your desktop, or in System Profile's USB column, then you have a bad USB cable or a bad USB port either on the camera or on your Mac.

What model Mac is it? Some earlier models only had USB 1 and they can be problematic when trying to connect a USB2 device.
If you look in the system profiler (go to about this mac and then select More Info) does the drive show there under the USB tab?
Does it show in Disk Utility (in the Utilities Folder) as an external drive?

Disk e? are you running xp on an intel mac? if so, then the drive letter probably changed. Windows does that now and again. Open up the my computer icon, then plug in the disk while looking there. The drive that shows up is the external.

Not running XP? then possibly something wrong with your drive. Open up the System Profiler (located in your utilities folder) and check under the appropriate section (USB for a usb disk etc.) and see if it shows up there. If not, try rebooting with the device connected. If still not showing up, check it in a different computer, see if it shows up there.

If you are still having trouble, let me know and we will open up the console window and have some real fun!

Easy, FireWire.
Connect the 2 with a firewire cable. If reading off the laptop, for example, reboot it & hold the T key down while it boots up. A large firewire symbol shows on the screen indicating FireWire Target Mode. The laptop should be showing up as a firewire drive on the other Mac.

Connect the 2 with a firewire cable. Reboot the Mac you want to read from & hold the T key down while it boots up. A large firewire symbol shows on the screen indicating FireWire Target Mode. The other Mac should be showing up as a firewire drive on the other Mac.

How are you connecting to the printer?

Macs do NOT connect the same as PCs, check the manual for connecting via the Mac.
