As I reported inĀ UQ Communications Data Cards and Chip Vendors , UQ Communications UD01SS is actually Korean Modacom‘s device, using GCT Semi chipset.
None of UQ Communications devices support MAC OS or Linux, which caused discontent in the Japanese technical community (Early Adopters and Apple Fans).
But when checking Modacom website for similar WiBRO devices, they do support MAC OS, which makes me think Shinsei Corporation or UQ Communications didn’t want to deal with the complexity of supportingĀ Operating Systems other than Windows (XP, Vista) at this time.
